1) The donations to the legal crowdfunder are anonymous, so Null doesn't know who's donating to him and 2) Turkey Tom already has a thread on KF where they constantly drag him and his girlfriend. By your logic Turkey Tom should be one of the very last people to want to donate to Null just because he was a thread. Yet Turkey Tom doesn't seem to care that he has a thread where strangers are disparaging his girlfriend all day long.
Are you perhaps familiar with the Youtuber
Jeremy/The Quartering? I have mentioned him here on OF before. Jeremy is Sektur-adjacent and used to be on Livestreams with Null and other Sektur people during #GamerGate. Unlike a lot of Sektur people who fell into the margins, The Quartering has over a million subs on Youtube. He mentioned #DropKiwiFarms when it happened in 2022 in a video. Clearly he's not too worried about getting a KF thread. In fact, I suspect The Quartering would DDoS KF more effectively than the troons do just by pointing his million+ fans there.
Now, how likely is it that The Quartering was one of the people who chipped in and gave Null a large amount? Given that The Quartering already came down on the side of KF in a video during the campaign? I mean, really, who other than multi-millionaire Youtubers like The Quartering and Keemstar who run big Drama channels would think that something like KF is worth salvaging?
You've offered an argument for why Youtubers would want to avoid donating to Null... but you still haven't pointed out another possible large donor. Who else would give 5 figures to Null?
Michelle Malkin, that same Philippino woman who supports Nick Fuentes?
Kanye West? Who?
