@LMAO is flooding the site with random communities because they’re salty about being banned for claiming too many community names. They claim they’re trying to “fuck your entire site up” but I imagine it’s a relatively quick fix to delete all the communities they’re creating, LMAO.
Doesn’t help too much, you can generate infinite email accounts with gmail for an example.
Manual acceptance of each and every user helps, but it’s not sustainable.
