server admins reserve the right to do whatever they want. you can complain all you want but it doesn't get anything resolved... especially when you're posting on a public forum instead of talking to them directly.
there is nothing you can do against a server admin, much less a server owner
especially a server owner who was generous enough to allow tempus to be run on them so that the europeans get a speedrun timer.
stone (and others) have been posting random unrelated garbage on the forums as of late (some of which I have removed because they were extremely bad). it's not like stone hasn't had a record of being somewhat irritating as seen on youtube from many of the users (recall the "originality" rant)
if you feel so inclined to be right, maybe you should start up your own european jump server in which you can ask rob123 to allow you to run the tempus plugin on it (although there is the obvious chance that he will not accept such an offer).
this isn't exactly a one-sided argument- both sides make valid points regarding their frustration, but in the end server admins do have a final say in it. especially when the majority of users are not defending the victim here in this case.
