@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.
Whether or not Lemmy supports this at this point, I dunno, but it’s easy enough to code your username verification to remove all +s and periods before continuing to ensure uniqueness.
Period can be removed with gmail emails. However, for +s, the whole part after + and before @ needs to be removed if removing+ as that part indicates the folder emails come to. Yet, the same issue would still remain for any Google Workspace emails as they also support + but doesnt end with gmail domain.
Ah yes, you corrected my logic on the +. Thanks for the added insight on the Google workspace.
