slime jumping

So when I got on the sever "which is my favorite" I wanted to play some games and I just loaded in and then it say that ive been banned for 90 days by a watchdog so can anyone help me with this? Thanks and have a good day! And the banned account was SlickBoy509

Really fun stuff was going on at 9pm - 10pm (for me) to end your day softly :) There where alot of people, staff and we where just talking a bit and stuff and joking around Oh and also the water was Slime, with also a high thingy to go on and jump off, this one was way more higher then 2 days...
