Sure, you could say I have a grudge against him. Like the OP, when I put in my ban request for one of Cicero's alt's, I had no idea what I was getting into. He trolled the ban thread, flamed in my clan thread and even threw a few of his lackey's on me for some trollolololing.
Funny thing is, nothing was done about it that time either. So I feel like I owe him one. I mean sure, he only abused the poll system with me. He only tk'd this guy because he felt that "his kill" was stolen. It's not like there's a LITANY of evidence/people against him, without any action being taken as far as I can tell.
Sure, you could say that this kind of thing breeds "haters" amongst the community. Sure, you could say I have a grudge against him.
(For instance, I was given a 48 hour ban from YOU Tenne when I team-attacked - not even teamkilled - on my very first offense, yet Cicero gets a warning?)
