tidus1097 I would avoid using the light blue color in your signature since it is too subdued... 
What's your opinion? We've not yet made the decision. But I think he should not participate at the very beginning.
I think you should pay him the coins you owe him, and it is up to you to decide if you continue to allow him in your program.
I think it's ok to not pay someone if they have an alt with negative trust, but you need to make that clear in your terms. Since you didn't have those terms when you signed Tidus up, you need to honor your agreement and pay him for the advertising he has given your company so far - you can't just unilaterally make up a new rule and apply it to past agreements.
+1. OP should honor his commitments & paying tidus1097 what is due to him for the post he wrote.
So let's say tidus1097 does change his signature (he claims this one was just a work in progress), will you give him the coins he earned in your signature campaign?
