Do this and it would create an auto-alert and your account would be blocked.

This is for the reason that the QL auto-bot (as they called it) will be alerted that you're a spammer thus you get blocked.

It happened to me once...and so some of the QLer here who were posting legit ads like yours.

The rule is: you could only post one ad a day...wait fro 24 hours to post the other one. Its a bit tedious, I know but that keeps spammers away...
