I had one (edit: multiple accounts) with a gazillion nsfw threads linking to multiple redirects (something with guru, I ran them through an online scanner). My adblocker nuked them instantly though but there's potential malware behind them.
I successfully blocked all of them at the moment, but that's only good for me of course. I'm hoping the mods can find a moment to go through and block all of them. All were created yesterday, all are accounts from kbin.social and all have only been posting links with strange domains and badly written porn keyword titles.
