There have been a few reports of users getting "exceeded maximum number login attempts" messages while using the forum. I suspect this is a new breed of spambots attempting to seize control of existing user accounts, to bypass the new user registration.
Basically, there's not a lot we can do against this, but the forum adds a captcha if you fail a login too many times, which probably makes it impractical for bots if a secure password is used.
So make sure you're using a secure password. Any single word used as a password, especially if it can be found in a dictionary, is insecure, because those are the ones bots will try to guess first. Check you're using a password that's a mix of letters and numbers, at least 8 characters long, and ideally doesn't contain words. For example, if you remember the phrase "three people met in a pub and had two drinks each", take the first letter and use numbers, and you have a nice easy-to-remember secure password: 3pmiapah2de. A bot won't guess that
(Don't be a dummy and
actually use that example, though...!)
Hopefully if everyone double checks or changes their password, we won't see any accounts being hijacked. We haven't spotted any hijacks just yet, but it's worth being cautious. Don't forget to report any posts which appear to be automated or spam. Thanks!
