Administrators can block users for any reason regardless of with or without reason; unless it violates Terms of Use. Although this freedom granted to administrators is planned to be reevaluated by Fandom staff in future, nothing can be done for now.

Also, I'm not going to pass judgement without really knowing the situation, but it's always good to evaluate if there really was no fault of your own in case you got blocked. A block resulted from ignoring the wiki's policies and/or administrators' warning, or causing disruption isn't lacking a good reason.

And if you haven't done so already, you can also consider politely contacting the administrator who blocked you and appealing your block. See User blog:Sannse/How to Get Unblocked.
