>>25098844IDs will deter lazier types of shitposters, but the determined types will just use it as alibis to falseflag going "seeee i'm totally not a samefag this is what people think (airplanes phone again for new IP)."
Now tell me, what kind of poster do you think most doxfags are - casuals who would go "oh no my epic falseflag plan was ruined because I am too lazy" or hardcore schizos who relentlessly attack for months on end and already do use any means at their disposal to evade bans? It's the latter.
