For a billion dollars? Do it and use the money for ddos protection so the forum will never go down.
I have some first hand experience with keeping a site up while being attacked with abuse reports, and in my case it was literal Indians sitting in a sweatshop in India getting screamed at by their boss to go after the site, when not taking phone calls off their dialer telling elderly stupid people that they owe the IRS and need to go to CVS and buy and read off the serial on the back of a fully loaded Google Play card.
Stop registrar attacks by moving the domain custodian to njal.la
The faggot that founded NJ was an OP on The Pirate Bay. They mail back pictures of their butthole to takedown and DMCA attacks. Troons and SJWs hate this registrar because they respect no ultimatums.
Do not ever give CloudFlare your real IP addresses
Use cheap VPS instances that are small, only 2 cores are needed on each, and have them all reverse proxy all the requests to the real host IPs. CloudFlare will disclose every byte of the account to ANYONE who asks. They even disclose payment details when they get sent a fake lawyer demand and that includes IPs from your account login history and prior IPs your DNS pointed to.
Do not ever give CloudFlare your real IP addresses
I have to repeat this one again because if you let the troons know where the ingestion host IP is, they will go after the host itself. Linode, Ocean, and all the other big hosters all bend over and take the fisting when just a single troon files a fake abuse report, then your VPS node gets shut off.
That is why you only show CloudFlare your reverse proxy IPs and never tell CF where the content really lives. It's easy to spin up cheap new VPS nodes, copy the proxy conf files over to replace a dead node that was taken down by a hosting abuse report.
Prepare to use your proxies to rawdog it
You can hit ClouldFlare with an intro letter from your own lawyer and let them know that withdrawal means denial of service, given that Keffals has a lot of skids who are also femboys, sitting around waiting to launch their python scripts at the site. You can have up to 5 A dupe records in your DNS to distribute the load with roundrobin, the oldschool way to spread users out.
You can actually get pretty far w/o CloudFlare if you are on top of your throttling game. You have to have throttling scripts anyway because CloudFlare does not protect you against POST flooding.
DarkNet the Fucking Site on the side
Set up a proxy to KiwiFarms on I2P and on Yggdrasil. Most skids are terrified of darknets or too stupid to figure out virtual IP6 vlans. Then find a faggot to post a list of instructions on how to hop back on.
There's no way to take down a DarkNet site short of going to the physical host and yanking the cord out of the wall.
Troll CloudFlare
Remember those reverse proxies? Only takes a few mins to bake a new DNS, recycle the VPS proxies to get new IPs, and slap it all back on to a virgin CF account. Then the troons have to spin up the whining machine all over again. You can keep CF support running ragged trying to deal with Keffaggots.
