lemmy.world is a victim of an XSS attack right now and the hacker simply injected a JavaScript redirection into the sidebar.

It appears the Lemmy backend does not escape HTML in the main sidebar. Not sure if this is also true for community sidebars.

I mean I get that he's in some sort of one-way findom relationship with spez but that should be done without harassing other people— we didn't consent to it.
