@MattDavis,
I'm not a moderator - I'm immoderate!
Anyway, tags can be nursed off the list. Let's say the subject is politics, and there are a bunch of tags someone added like libtard, idiot, rightwingnut, or similar.
Open the thread, and add your own tags - for example, politics, U S politics, sequester, voting rights - basically, what the thread is about. Sometimes it takes very little to change them, and sometimes I've added as many as eight without anything changing and then add a ninth, and all the insulting tags go away. I've no idea how that works.
On voting down, I do vote down threads by bots (there are ways to tell).
There is a way that you can choose to see all threads by selecting that choice in your preferences. There is a default thing in place otherwise, that will make a thread with a huge amount of thumbs down then not show up for you....
so to not have what threads you see affected by other's thumbing choices, you have to purposely go to Preferences and choose No re collapsing unpopular threads or posts.
Ah, I see there are two more pages and Jes explains stuff. Oops!
