As already said, Zefan solely said the reason for his banning was due to the sig. If you're calling me a liar, then you're calling him too. I didn't just make it up for the sake of it.
Would Basmic's sig be allowed now?
Plus other warnings, it even says it in that thread he linked.
Asked to remove the sig, to which he did, then made numerous (two threads) about it complaining.
That's what I got from it.
