The issue here is, is that post a direct copy of the link?
Yes.
And does that deserve an instant ban?
Yes. See the rules here:
https://bitcointalk.org/index.php?topic=703657.0 - "33. Posting plagiarized content is not allowed."
And also were the moderators biased because the user made an unsavoury post?
No. They were upholding the rules.
And when would we have anyone protecting the rights of the lower ranking members?
You have the same rights as everyone else. If I plagiarized, I would also be banned.
Since you clearly haven't, I would suggest familiarizing yourself with the forum rules before posting any further.
