Thread:Project:Support desk/Stopping Spam?/reply

I've tried to create new users on your wiki, with no avail: There's no create account action, and the api doesn't allow creating new accounts.

Your wiki seems to be compromised.

I see you have Extension:UserAdmin installed. I don't know if it has some vulnerability that would allow creation of such users.

I recommend you to investigate the source of the problem. For that matter, check your server's access log (enable them if they're disabled). That would tell you what URLs they're using to create new accounts, so you can identify the "hole" where they create new accounts.
