For something to be against the rules, you need to find the rule. If you're asking if it is against FANDOM's Terms of Service, the answer is there are no parts of the ToS that prevent an admin from blocking someone for no reason at all.

All that said, when there is a claim that a user is blocked for no reason, but we don't know the name of the user, that claim is usually not to be trusted. However, if we know the name of the user and the wiki, we can look at the block log and confirm that at least no reason was given. For now however, I don't trust the claim.
