Your post is allowed, and there is no need to check the board rules for this.
MERB moderators set the sanction for the original rule violation, and that was a ban. Our methods of communication are very effective. If they were not, you would not have known that he was banned, right?
The first time I saw Special K's signature, I was confused. I did not know why M2 would have posted that message in that topic, then I saw it was a signature. Imagine if everyone did this. Would MERB really be that useful then?
If you want an official rule that covers this, try this:
v) Refrain from posting the same thread topic in multiple sections.
If you want to post about the incident in the original topic, go right ahead.
Your signature was not your opinion though. It was Mod2's, so please do not tell me I am leaving you with hardly any way to convey your opinion.
