I don't expect that you're going to accept any facts that don't confirm your biases, but surely you can recognize that a list of other campaigns that have used a fundraising platform is not in and of itself proof that the platform has been misdirecting donations. If Airbnb posted a list of its top 10 highest earning hosts, that list would not prove that your guests' rental payments were going to those hosts instead of to you.
It's not really the case that a fundraising platform has no oversight. Not only are registered nonprofits subject to regular external audits, they also have their own clients to answer to. It's not too hard to launder dirty money through a small nonprofit for an uncontroversial cause like homeless kittens, but if you're handling funds for a politically charged hot button issue, you're under a lot more scrutiny and you have to keep meticulous records, as you have opponents in high places eager to pounce on a mistake. Notably, no public records show any evidence of what the pundits you're parroting accuse ActBlue of.
Of course I don't feel anyone should donate to any organization unless they genuinely want to support it, but it's not necessary to invent a nonsense narrative just because you disagree with the cause.
And I guess you're not particularly familiar with maps, but Seattle/CHAZ is rather far from Berlin. You can dispute that fact if you want, but I'll have to ask you to drive between these two cities to prove your case.
