Yeah, if you are genuinely targeted but not at quite the same level as KF, reverse proxies are a godsend. If I was in that situation I would be basically just be cycling through domain names and random VPS providers that take crypto, and setting up a new Cloudflare account every time because it hides the actual reverse proxy location for a while and also fuck that faggot Matthew Prince.
The problem is that that's very bad as far as maintaining a consistent clearnet brand... you want users to just be able to go to kiwifarms.net. Sites that aren't actually being targeted but pretend to be like Daily Stormer don't do this... they stick around on the same domain for a long time, because it would be bad for the brand to change URLs too frequently.
