My friend you maked a huge number of posts in a day....
You joined on 20 November and posted 250 posts in just a day.. It's looks like spam because you are posting on every thread and doing spam.... Post only in limit.... I think this is the reason of banning(this is my think)
Thanks...
Bitcoin is kind of sensitive. My friend once told me that there is a limit when posting. If you post from time to time and reach the limit it might ban you. And as I can see, he/she clearly crossed the line of posting rules. Maybe it was misinterpreted as spam because of the amount of post in just one day.
Nope. As long your posts are on topic and contribute relevance to the discussion then there will be no problem even if it goes over tens to hundreds but it makes no sense to have 400 posts in 4 hours (for example). In this case, it is impossible to create a constructive post for about 36 seconds per post (it would be much lesser if you try to pick a good topic to reply).
P.S. Refer to the above posts for the "real" reason.
