There is always that one cunt that always has to make it about himself, isn't there?

Either way, face the fact. This is the first time it happened. Sure, SAMP used to have activity problems at times, but never to this extent. Never to the point like this. And no, it is not that the "mod is 12 years old". VC:MP is about the same age and still kicking, and people don't seem to get tired of it anytime soon. In fact, it seems that the older it gets, the more people join our community. As I repeated time over time - it is the SA:MP community that can be really unbearable that probably motivates people to leave.
Just take a good look at yourselves. Instead of working on reviving the server and looking for compromises, all you do is whine and complain on the forums, while that time could've better been spent actually being in the server and contributing to its activity, no? You all complain about how shit roleplay quality has become, but don't want to give up your huge arse weed stock and you know that the next time you get in game, you'll just be grinding drugs either way. Everyone in this part of the community gets so offended over everything that simple banter can get you banned. There is no light-heartedness or open discussions. Everyone is either being overly sensitive or trying to suck up to the admins. Hypocricy is a huge problem. There is no honesty.
Stop blaming the mod or the game or its age. You guys yourselves are the problem. You come to the forums and cry about "how shit Argonath has become", but you still remain on the forum and follow the development of events, because deep down you know you still care and want to come back if it ever gets better. Were I incharge, these hypocritical bastards would've been banned with no chance of return.
TL;DR - start by taking a good look at yourselves and then you'll see the answers why you are in the situation that you are in.
