Forum:SH:Custom signatures between sites

On the Signature policy page, it states:

"''How do I bring my signature into compliance here without having to change it across all of Wikia?

''As Wikia uses a single user database for all of its wikis, you only have a single set of preferences shared across all wikis. This can create a problem if you establish yourself with a fancy sig on a few other wikis, only to try to become active here and be told that your signature does not comply with the above rules. Instead of simply changing your signature in your preferences and sacrificing your fancy signature across all of Wikia, there is a way to maintain your fancy signature elsewhere while complying with this policy here.''"

Pardon if my reading comprehension is apparently terrible, but is this meant to address the problem that one's custom signature for one site carries over to all other sites? That is, by default, you cannot create a custom signature unique to each wiki without going through the steps given in this section? Why else would a fancy signature on another wiki potentially contradict Wookieepedian policy, and fixing it will "sacrifice" it "across all Wikia?" I did not encounter this problem. My custom signature did not carry over to the Assassin's Creed Wiki (although my preferences) did, so I simply had to create the custom signature again for that site. So I was curious what this meant Sol Pacificus Telepathy 03:12, March 11, 2016 (UTC)
