Seems like some b*stard 1 has been entering other peoples accounts and messing them up, or worse, deleting them. The most likely ways of this happening are
they share your computer
they guessed your password
If someone can GUESS your password, it is RUBBISH. So change it. Passwords with numbers and letters mixed up are GRATE. If you know anyone who has done this, give them a kick in the shins. If anyone gets caught doing this, they will get either
banned
a prize
Back in 2000 on popex I would have asterisked this out, but here I've replaced it with a similar unicode asterisk symbol to stop it messing with my markdown styling.
The content here originally from my very popular (in the late '90s) site popex.com. Some of this contributed by other people, so mostly editorial originally created by me. I shifted this content here when the website finally closed down at the start of the '00s. Hopefully this ignites memories if you find it.
