With feedback we've received as well as through our own observations, the mod team has amended the spam rules to now include tag spam. The rule addition can obviously be found in the rule book, but I've copied it below as well (If you have any questions or need clarification about the new rule addition, or any of the rules in general you are always welcome to pop by the ask a mod thread, or pm any of us directly):
Spam includes, but is not limited to: multiple duplicate posts in one thread, posting the same picture multiple times in one post, use of unrelated tags in a thread, posting the same thing in multiple threads, excessive emoticon spam (more than 15 in one post), and creating new topics/threads one after another.
Tag Spam - 1 point
It is considered to be tag spam when a thread contains tags unrelated to the topic of discussion, which are being used to generate thread views, or antagonize fandoms/users. If a user chooses to add tags back in after a moderator has removed them from a thread, their posting rights will be taken away for an extended duration at the moderator's discretion.
1st offense: 0 Point Verbal Warning + unrelated tags removed from thread (Warning Log)
2nd offense: 1 point + Taking Posting Rights Away: (1 hour)
3rd+ offense: 2 points + Taking Posting Rights Away: (1 day)
On behalf of the mod team I hope everyone is having an amazing, safe, and fun holiday season. Be good to one another in this coming New Year!
