I guess it's because all your posts are in the off-topic section.
Plus they are all small replies.
This forum is based on bitcoins. So, you come here to talk about crypto.
But since you just come to talk nothing and try to rank up based on that, you got banned.

so is this temporary?
Well, it depends. If it was really just unnecessary spam then usually it is temporary. But if it is a repeated occurrence afaik you'll get a permanent ban. From most of the meta threads that i've read it's usually a 14 day ban. I would say that spam was likely the cause of your ban, because all of your replies were just 1 liners in either off topic, BS threads or megathreads.
However since you were banned, you created this account and decided to post outside of meta. This qualifies as ban evasion, and Vod has tagged you for it.
Ban evasion will result in a permanent ban.
