I think the admin team needs to decide on a clarification of the rules regarding whitelists and items that are not on them.
I have noticed some (at least one) of the devs banning a fair number of people lately for using weapons that are "not whitelisted".
I know TF2C has had some whitelist enforcement issues lately so some of these probably stem from that and some from servers that just flat out don't have a whitelist. The problem is, how is the player in the game supposed to know what whitelist should be enforced? Each league has it's own whitelist and when joining a lobby as a player I have no way of knowing weather the leader set up for UGC or ETF2L or one of the other options. So now if there is no whitelist I'm not sure which weapons I can and cannot use without getting banned, aside from the obvious weapons that are banned in all leagues like the pomson. Furthermore, I am only familiar with teh UGC whitelist as that is the league I play in so even if I did actually know which league they set it up for I wouldn't know what ETF2L doesn't allow that UGC does and might run a "banned" weapon that I think is okay.
In addition to this, the very act of banning these people implies that server operators are not free to modify their whitelists if they so choose. I know of one server owner (who happens to be an admin) who bans phlog on UGC lobbies even though it is now a whitelisted weapon, should this really be allowed? If a server owner can't allow weapons that leagues don't should they be able to ban weapons that leagues don't? Maybe if they use a modified whitelist they should be required to mention an modifications in the lobby description.
My personal opinion is that it is the server owner should be able to modify the whitelist but maybe should have to mention any mods in the description of the lobby. Players should not be punished for using weapons that a server's whitelist (or lack of whitelist) allow them to use in game unless server operators are also going to be punished for not having a whitelist or for modifying their whitelist. But of course that is just my opinion, I'm sure others will think differently and really only the opinion of the people running the site who make the final decision really matters.
