Some simple solutions for AnH:
1) Ban people who report others for their opinions (that aren't bannable). Block is an obvious option that is enforced across every forum on the internet, why is it such an issue on this forum?
2) Ban bait posters. People always complain about "people taking the bait" but never address the issue with the bait itself. You wouldn't have 50 socks of retards if you ban people making this obvious bait. You kill the bait users you kill the bait responses, and those members that people like who bait? learn new claims of arguments. Even if you were to ban all the people "taking the bait" you'll still have 50 posts of certain users posting the same true and tired bait. Kill the roots and the tree dies. Some bait responses can be productive but it's contextual there.
3)Outline specifically what posts you don't want. (Not just fedposting claims

Don't remove free speech but make the posts have some quality outline. (Also take into context of the posts: comedy/etc.)
4) Slap fight regulations. I think a few here and there are fine but constant just force them to PM fight if it's such an annoyance, block the users from interacting each other or ban them.
5)Bring back all stickers. If someone complains ban them. Simple maturity tests. This has also been done on many sites I've seen when this issue arises why not here?

Some other notes:
It seems to me there is a lot of exaggeration over AnH users or very stereotypical misconceptions:
The claims most are refugees banned from other sites is laughable. I'm not saying there aren't some users like that, but even with my own obvious sperg antics on sites like Twitter and so on I'm not banned and am also on almost every social media site and or forum, that's known, (And without sock accounts) it's very likely many are not "social outcasts." It's more that most sites you can't be completely honest or say any reality of truth or what you perceive to be in regards to certain topics. People often use euphemisms instead of saying directly what they want to say almost as bad as working at Wal Mart and bringing up unions. Why wouldn't they post on a site where they can do a 180. If you think it's merely over the word "nigger" you are daft or tone-deaf.
"There all politispergs/autists who don't embrace any other discussion." It may be true for some users, but honestly some times I stop in to check news from random sources, because each topic I liked to discuss was either borderline dead from a long time ago (Necroing is dumb), most didn't discuss to the level that I see on other forums which made it pointless, or I just read the topics without posting in them. (Whether someone ninja'd something I'd say, un-necroed topic/etc.)
The other problem is the "It's a circle jerk." When people come into the topics and basically posts new-to-the-internet arguments, maybe it's not the AnN posters that are the problem but the dumb-fags who have no concept of things perpetuated since the start of the internet. Most don't even try to make an argument and the rest seem more petty and upset people don't conform to their narrow political and social worldview. Before you go "What about anh users" then debate them, block them or shut up.
"B-But the hugbox" Which most of the posters didn't even stay in the hugbox only and some merely joined it as a social grouping being invited into it. It's not like other groups weren't forming in opposition though some of those same posters are pretending otherwise. Hmmmmm..... Like this shit isn't new on forums. Social groups do this without disrupting forums all the time. "B-B-But HHH sperging and they fear him or whatever people claim." If you believe that you're delusional. I think most people do it to hate-like or create a "rivalry sentiment" such as becoming friends with known trolls, or hate-fucking someone that antagonizes you. Like I said it a lack of perception on why people believe this shit.
"Combativeness." Hahahahahaha! This is the complaint that reeks of new-faggot on the internet argument to me. Welcome to the internet where people are generally combative in almost ANY social media platform even in forum groups because of power structures or what have you. Next people will be crying over cyber-bullying or some shit. The only way to not be combative is 1)Conform to each others opinions on even the menial of things (Hmmmmm.....) 2) The people whining about this shit should stop taking themselves so damn serious and realize they are just as combative it's just a problem when their "opposition" does it. Fess up, and be honest. If they're harassing the other users outside the AT then ban them. Simple solution.
"But multiple people jump one post causing them to sperg" Which some present multiple different arguments confronting a counter-argument, scary that's almost how discussion, debates and arguments work. Like seriously this is new-to-the-internet shit.
Any board about politics is going to be ruthless as politics is based on power via accepted or "correct" concepts. Again I redirect to combativeness, and politics is hand in hand. Now with how tribal it is, you aren't going to instantly see just laughing at retards in politics. Some like to downplay their own biases but it's pretty read between the lines from their post. The sticker issue proves my case. They want their claims to be considered "positive viewed" and everyone else as dumb or more favored vs disfavored. Come on. Why lie? Anyone could post a counter argument if they felt so assured, the problem is said posters know their arguments are dumb and are blaming "circle jerk" instead of self reflection that maybe they're not the elite genius they thought they were. Oh no. Maybe your counter arguments weren't that great and that's why you got dogpiled not because anH is alt-right central and you're a genius being beat down by fascist and some know they're trolling which is fine in moderate doses.

In regards to the moderation the problem comes from having people who aren't partisan or are as anti-politics as can be without falling into a "accidental wing" by their beliefs to moderate it if possible or someone who can bypass their own bias and consistently prove they are capable.
One last note with Null not knowing many of the members, honestly I'd love to see a lotto where once a week or month Null selects a random user and just harasses them for a day and see how they react. Mock their posts, edit their title and avatar, etc. just harass them for a few hours. It allows him to release steam and get reactions out of users he might not interact with normally and if they go to overboard over the antics ban them. This kind of thing would also lead to social interactions from other users who might see said user being mocked and you keep mentally sane people who can take a joke, get rid of fragile glass bitch babies from all sides.
That's my 2c.
