I don't know if you are actually participating in a discussion or trying to increase post count and thus, payment. This is same with admins. They can't know either. So you should put more effort in posting. Honestly, your posts looks spammy to me.
Everything is subjective, sometimes 100 meh quality posts spammed in a 1 day time frame catches a moderator/admin's attention more than 10 poor quality posts. There aren't post limits, however it goes without saying that at a certain point its hard to maintain post quality. People aren't banned on a whim, time is spent investigating especially in these situations where it isn't copy and paste/quote/smiley face/ +1 spam. Sometimes people spam meh - ok quality posts, but when you read the threads they are posting in, their posts aren't completely related or they are just reiterating prior posts to get the post count up or they are posting in threads that have already drawn a conclusion, and they are just reiterating points. People that post very frequently especially those with paid advertising signatures catch more attention sometimes than small spammers. Trust has no impact on bans or ban duration, while admittedly account age/status does minimally if I'm being honest. No one has a free ticket to spam, but a newbie with 5 of 10 of their post count being low quality are more likely to get a severe ban, than a member who has been active and posting high quality posts for a while, and slips up and spams a bit.
As I said, there are no rules on post count, you can post every 10 seconds if you wish, but the chances of your posts being quality decrease when you impose quotas.
I highlighted part which is the most common issue imo
will i get a perm banned next time?
I tend to consider sig spam bans a class of their own, as in I don't generally lengthen the duration due to previous bans, unless you are truly a bad poster or there are some other special considerations.
Second what is sig spam? Is there a sticky that has a in depth answer like less than 10 words, posts within 5mins, 100 posts a day, 300 a week etc
A tendency to make posts in order to boost your post count, and you have an ad in your signature, particularly one that pays you per post. There is no secret invisible line that you shouldn't cross in terms of numbers, it's mostly subjective.
There are people who just don't post very well in general, post "too much", or don't really have anything to say, they just like to participate in the community and post. This itself is fine. But when you add an ad to these kinds of posters, it's difficult or impossible to tell if they just aren't quality posters or if they are attempting to boost their post count. I used to err on the side of caution here because I do
not want to ban the former, just the latter, but too many of the latter are slipping through the cracks because it's very difficult to gauge someone's intentions. This is the main thing that has changed lately.
