Well, honestly I wouldn't be that much worried about activity. That's not the most important part of an admin applicant as long as he can join the server on a regular basis to ensure his administration duties and as
@Ed said that's also up to the server manager to judge whether he is active or not and whether the activity factor is important or not. In D2 for example, the activity factor is not really that important since admins can't always be consistent and join the server with the same activity they used to do the time they applied for it.
@Frendy I don't know how you got confused to be honest, this was perfectly clear, but well, maybe your English level is not that good after all. He said that he used to play CS:GO surf in an other server but that from now on, he'll only join the Ambrosian one. And he hasn't recently become an admin. If you only took your time to do a bit of research, you would realize that he is an old member, that he has a lot of qualities that would push any server manager to accept him in their team and that he has already administrated lots of servers. Moreover, he has done a good job so far and he has never been problematic to the community (or I haven't noticed it).
@Unreal | AS, I don't know why you got involved to be honest and why you are going off-topic. Frendy got confused, I understand why he got confused since it happens to all of us but what I don't understand is why you are defending him. Your opinion is very biased and doesn't serve any purpose at all to the main topic.
So yeah, I'm giving my support, even though it's not that much necessary I guess.
