Did you try to appeal to the supermods or the admins? Granted, the admins probably would have referred you to the supermods, but there is an appeals process in place for when you feel that the mod who dinged you is not listening to your reasons.At the end of the day, this is a forum on the Internet. While usually a fun, interesting and often educational place to visit, I highly doubt it forms one of the most important aspects of any members' lives, including the moderators. This is a place of relaxation, fun, and light discussion, or a hobby if you would.
However, I think the moderators don't see it this way. I think the moderators see CFC as their own personal domain, somewhere where they have control over the posters and somewhere where their egos can go a little over-the-top. A forum of this size does need moderation, yes, to protect the more vulnerable posters from harassment or harm, and no one can argue this point otherwise. But CFC's mods take it a step too far, where we all have to conform to a set of rules that may as well be named the Commandments. One little deviation from these Commandments, be it in the interest of making a point, making a joke or having some fun, and you will receive punishment for it. That's not fun.
I'd like to refer to my complaint on the first page on this thread, to continue the discussion regarding mod's PMs and such. I probably should discuss this via PM with a moderator but I've already tried that; the mod in question simply stopped replying to me once I shown him that I didn't actually create a spam post and it was meant to be a joke. However, no efforts were made to remove my card. They just stopped responding and assumed this behaviour will go unnoticed, so I am glad that this thread exists where I can explain this.
They will be ignored, as I've just explained. Perhaps if the mods were to prove they actually took these complaints on board the tensions would ease a little bit. But the general opinion is that nothing gets done. The posters can't all think like that by sheer coincidence, can they.
Try it, and if it happens then you'd be justified in feeling that way. There have been plenty of mods here who have said "PM us." So try it.
