The moderators can dish out a temporary or permanent ban only when the offense committed by the user involved is satisfactory enough to meet up to that kind of decision, I think for now, he has been enjoying the grace of having deleted posts, I believe that one day, something will still push him to commit what will attract having a ban on his account, after all, everything he is posting could be accounted for using ninjastic thread, let's just keep reporting till he finally landed himself where he never expected, there are many other members like that yet to be discovered.
Spamming and shilling at the same time is not allowed in the forum because it has zero value post most importantly that he is just duplicating thread. You can use the rules below as reference.
NOTE: This is meant to serve as a reference/educational/informational thread, NOT a rock solid list of rules.
1. No zero or low value, pointless or uninteresting posts or threads. [1][e]
Examples:
1. Such posts as "SELL SELL SELL", "I agree", "+1", "Support", "Watching", "Interesting", "LOL", "SCAM", "LEGIT", "FAKE", other one word posts, posts consisting mostly of swearing, quote pyramids, useless introduction threads, threads about a topic already recently discussed in several other threads.
AFAIK. There is just a minimum threshold of spam post before user get a ban punishment. I don’t know exactly what’s the exact amount but a frequent deleted post will surely result to temp or perma ban.
