Creating a new account to ask why was your old account banned may only cause more problems for you. Looks like your last post was only 20min or so before starting this topic and it was a bump.
No, it was several times explicitly stated by mods and staff, that
creating an account to discuss a ban is allowed. Just dont post outside of meta or discuss other topics within meta.
My main account "btcvilla" was banned from posting and sending private messages for 14 days, why was I banned, is there a way to get unbanned early?
14 days is a typical
first-warning-you-are-spamming-ban. It used to be less, but BadBear apparently had enough. I only skimmed through your posts, but the majority (last 3 pages) look like one liners. I read some and do not think they contributed to a discussion. If these posts are the exception they are fine, if they are the rule, they are not.
As others have said, to get unbanned early will not happen, wait 2 weeks and come back. You are allowed to log into the account and read your favorite threads etc.
Keep in mind that you are not allowed to create a new account to post anywhere besides where. That would be considered evading the ban, which would prolong your ban and increase the chance for a permaban.
Edit: If you need to keep in contact with customers etc. you can change your signature to
I was banned please contact me via ->
