Hackers have started to use BBS's to help a whole new generation of spamming.
They use them as a source of ICQ numbers and ideas for hacking accounts.
I recently had my 10+yo ICQ account hacked (probably for good).
I recommend that if you have an ICQ account, and have displayed its number on BBS's that you make sure that your email address and password hint are upto date and that your password is not easily guessed (No dictionary words, no dictionary words with letters for numbers substitution).
Dont use the same password for BBS's as your email or IM.
Otherwise you may find yourself like me.... without your ICQ account
(Damn I wish ICQ had sent a confirmation email before allowing a password or email change!)
