So... I see a never expiring ban on people who break rule 8. yet, what is rule 8, so I don't break it...
8. Keep alternate accounts within reason
We will be taking a very relaxed policy towards alternate accounts ("alts"), provided that people do not force us to take a stricter stance by abusing this policy. Alts are allowed, and will be permitted free reign across all fora, provided that they follow the rules for the forum they are posting in. FES has a history of alts that contribute to discussions in addition to the usual complement of spamming and trolling alts, and it would be a shame to try to restrict this.
There are two exceptions to this policy: one, an alt that is used for the purpose of furthering a main or another alt's argument without itself contributing a unique point of view on the situation ("sockpuppetting") will be immediately banned; two, an alt that is intended to impersonate a member either here or on the old FES will be immediately banned, and deleted if it is occupying the username of an old FES member, as otherwise it would bar them from registering here.
An alt breaking any rule that would ordinarily result in a warning can (at moderator discretion) be handled by immediately banning the alt account, and instead warning the main account of the person controlling it.
Edit:
It's harder to find the rules than it needs to be. May I suggest stickying them at the top of every upper-fora so that they're easier to find?
