Please keep in mind, while these are public servers free for the internet people to use, we (our community of members) pay for them. Because of that, we're able to craft our rules for our small corner of the internet.
I'm not saying you broke any rules and I can appreciate where you're coming from, but attitude and communication is everything. For example, this would all be over if you came in and said "Hey guys, love the server and the community you've got here. I got banned and not entirely sure why. I'd love to find out if I broke a rule so I can avoid doing that again, or if it was a simple mistake, no harm no foul. Thanks guys!"
There's still a chance for that, but that's your choice.
Sorry for any inconveniences.
