Custom skins only appear to you, and do not travel over the network, unless you have used a hacking program which does so.
Sites such as FPSBanana hold skins which, to my knowledge, are perfectly safe.
It is perfectly legal to utilize custom skins over online systems. They will only appear to you, and no one else will ever know.
