Good point. I’ll change it so that tl_0 cannot edit posts.
Reviewing one of the recent posts:
Looks like it was initially just garbage and then edited to spam, this would have circumvented Watched Words as far as I understand it.
Given that post edits from innocuous gibberish to spam are becoming part of the modus operandi of bots in their efforts to thwart spam filters, does the Discourse team think tl_0 should by default not be able to edit posts?
