As long as people are willing to engage with him/her, he/she is going to continue to post and break the rules. If the majority puts the user on ignore, maybe they will disappear into the sunset. Maybe being the keyword there as it's entirely possible they will continue the same behavior until some action is taken.
Particularly the unofficial rule number 13. In many cases he has been reported and posts merged but he has been warned that he should read the rules and follow them and he doesn't care:
I don't even read his wall of garbage. I just look at the date/time of the last two posts, and if they are both him I report it. This is the kind of attention he wants - I've gone through the same thing with many a determined scammer.
Reporting the same person over and over should spark a red flag for the moderators and bring an action, but so far hasn't. Are the mods even moderating anymore?
