Hurt no, but potentially slow thing down, yes. The more skins you have listed, the more the programs have to check against. Remember, it compares every user on the server against every skin you have listed. The more you have, the more stress placed on the system...which could cause some for you if you're running the program on the same computer you use to play with.
Mac170570 did a nice job in taking the time to list the skins alphabetically. It will make it a lot easier to remove double entries.
I don't agree with some of the clan skins listed. There is a huge difference between a custom clan skin and a bright neon one.
I'm in complete agreement with you on that one Druid. I think some clans/server admins are taking this skin thing way too far. It's gotton to the point now where I've seen players (including clans) making fun of and or insulting other players because they're using a custom skin; gotten it myself several times. There's a lot of really well done skins out there, that provide no advantage to your game but rather just appeal to you visually (i.e. I really like the Rainbow 6 or Special Forces type skins out there).
I know it's within the rights of the server admins to run the servers as they like (i.e. allow custom skins or just stock skins), and I don't mind switching to either mode, but this insulting stuff is just ridiculous. If people want to cheat, they will do it...whether you force stock skins or not, there's ways around it all I think people just need to lighten up a little...
Sorry for getting off topic...it's been eating at me for a while now
My list alphabeticaly arranged.........only skins that are bright-coloured and easy to spot in a game. If you wanna use the other long list i suggest you use DMW-scanner for it will allow only stock-skins.
The Breach and Clear one is harmless, not sure about the axis one. The allied one looks like one of the Tom Clancy Rainbow 6 type skins...black, gray, some white mixed in. Just an asthetically pleasing skin, no advantage.
