(Answers in bold)
Being new to YT, I have questions about suspension rules. For what reasons are members suspended?
This can't accurately be nutshelled. It could be one single event (attacking a member), or it can be several posts that add up to a suspension. Also, YT always tries to look at a member's situation as more of a whole -- and not just as that individual 'event'. For example, maybe a member's yorkie just died, and they flew off the handle about something...maybe that person deserves a bit of leeway. Can't really answer this as a black and white question...it's more like a gray area, for certain situations.
How long does it last?
Usually, the first suspension is 7 days -- other suspensions are often 2 weeks, or 3 weeks. Banning can happen if suspensions continue to be a problem. This is a passionate forum, so we really try to avoid banning so that all different kinds of members can be here. However, when someone goes way too far, it happens. Also, if/when someone is here solely to badger the community, or if they open accounts when previously banned...they are banned immediately.
Can you still post while suspended?
No. That would be grounds for being banned.
Is there recourse if you think the suspension is unjustified?
Rarely is a decision ever changed, unless there was some obvious mistake like wrong member was suspended (can't think of that having happened though), or creating a double-account wasn't intended, or somehow the wrong button was clicked on our end, or blah blee....that's all I can think of off of the top of my head.
Can admin or a moderator help me out here?
Hope that helped a little
