Is it really surprising that an unilateral ban of people without definite and clear reasoning [It appears so to a casual glance, at any rate...] would flare tempers and cause discontent? Especially on a gaming community that exists for the enjoyment of...you know, the people playing it. People tend to forget that in the large-scale arguments and big words and accusations that are painfully close to something I'd say about real-life issues, politics, and governance...
Let's try to be fair to everyone, here. The admins and devs are all volunteer, unpaid folk...but it is also important to remember that the operative word is 'volunteer.' Many have come and gone, many will continue coming and going. They're both quite important to keep the server running and things somewhat interesting for the playerbase...and again, the volunteer services exist for the benefit of the players. This is a video game. There is no other demographic to cater to. It's when the playerbase appears at seeming odds with the people who perform maintenance tasks as it were...things get dire, then.
Now then, I've called for stricter admin action against people who skirt the edge of the rules and make things rather un-fun for other players for a while. A fair few people have done so over the years. But if you're looking to weed people out for being detrimental like that...back it up. There's no need to rush these things out...gather evidence, and make your case for removing such players irrefutable. It's a regrettable state of affairs anyways, a dwindling community weeding out even a single member who had a constant interest in it is a loss that you won't ever fill. If people don't keep that in mind and end up doing the slamming regardless, you end up in a situation where people will (rightfully) believe that the ones entrusted with volunteer powers are enforcing their own view of who and what should be playing the game, and that is quite the problem. People who don't want to play that way will leave, and so the playerbase continues dwindling.
