7. Signature size. Signatures may not be over 6 lines in total height, as displayed in a forum window. Signatures may not be more than 150 characters and spaces in length, not counting vB Code tags, a limit that is enforced automatically by the forum software. Signatures must not be overly distracting to those reading the forums, as judged by the moderators. They should not have blank lines or lines consisting solely of punctuation (dashes, equal signs, etc.), or use vBulletin features, such as "INDENT" tags, that produce unnecessary vertical space.
8. Avatar and signature content. Avatars and signatures, as well as other profile fields, must comply with all forum rules, including those against profanity, explicit sexual content, and insults against groups or individuals, and cannot be in other ways offensive. Members will be required to change avatars or signatures that are deemed too controversial or that are particularly annoying to other members.
9. Simulated signatures. Signatures must be set in the User Control Panel and not simulated within posts, so that other members can choose whether or not to display them. You may not use automated software such as FoxyTunes Signatunes to insert content into your posts.
