This one is worse than a troll. I'd call them a flooder bearing Palestine flag on their profile picture but almost calling for unconditional Biden support under all posts and a lot of comments of the same posts individually.
On second glance at their full profile, this is mostly a bot account utilizing some sort of Cambridge Analytica-style, actually trying to undermine support for Biden through the spammy, braindead "I'm on your side, let's support this thing with the same zeal and rabidness we criticize the right-wing with" false-flag operation on social media.
