It is very hard to judje on these videos. The player doesn't do anything circled, plus he is running、 jumping. and he can also attack u and when with low hp he would rest to restore health. Also when you appeared in from of him from hide, the player started running from you. Therefore GM cannot take any actions as not being sure of the actions of the player.
No bots are allowed on the serever, however the video provided doesn't prove to GM anything. GM see the player running, jumping and killing the monsters. As soon as he sees the other player of the other faction he runs away.
GM is sorry if you're not happy with the decision, but GM never ban anyone unless we are sure about the violation by 100%.
Remenber No Bots are Allowed on the Serever ! But GM never ban anyone unless GM are sure about the violation by 100%! His 99% action show him in an abnormal state, but GM will find out any point which is reasonable, even its 0.00001%, GM wont ban him.
The other game's GM : try to find out any point which is not reasonable.
Euroaion's GM : try to find out any point which is reasonable. If found, the admins checked the video and there's nothing against their rules in it.
