IMO, there are much clans, and not manyt ppl ( i think NO ppl) know all clans. So... Why don't make an "official clan" Image for each clan? They'll have to sign up for it at *a* site, and each image will have a unique number. With that number, you should be able to check the clan stats on the site, and with that numbers, copying "official clan" images cand be detected fast. If a clan don't have a site, ppl who want to join the clan can ask for it, and they'll get it with e-mail, ICQ or something. The "official clan" site will be something like a page where you can:
-Enter the number, so you can view clan stats (for all visitors)
-Edit the clan stats (change member count, and that stuff, only for admins and clan owner)
-And something more, like viewing a clan list (for all visitors)
Maybe smart, maybe bad. Decide.
