I just deleted couple of accounts again, because e-mail used to register them was something that made me sure they are spam bots even if no spam was mailed. This was still merely 4 spam bots that have found their way to get in, despite the visual confirmation. We'll see how things go. If it was actually someone actual person who was supposed to be here, just register again.
NOTE: if you have no objections, please fill something for the profile. Location, comment that is something "personal" enough not to be confused with bots. If your nick, signature, and such are easy to identify on some existing person, account won't be accidentally deleted while cleaning forum.
