I certainly wouldn't give him money, but with how cowish a lot of DSP a-logs are I could see the appeal. Philburt's still gonna be broke at the end of the day regardless, he is uncomfortable unless his bank accounts its at $0, but at least you can watch the tards who are desperate to convince themselves they're better than him scream with rage.
As for why the ones who unironically do it do so, they're basically like tranny janny sorts. It's why creeps like Anonymouse who take pictures of themselves in diapers and who hit up children on Twitter will both mod for DSP for years and give him money. Anything to feel powerful and meaningful.
