i honestly couldn't get what you are trying to say, maybe i am confused.....
Yes, i am just one of those leecher on this forum. I haven't played L2 for a long time and just interested in seeing how much the game has growed. About amount of posting, if someone like the community, they will post, and will get a lot that is totally normal. Some people just love to chit chat, that is why lately blog are so popular. However, if you look through the forum, there are thousands of posts like "lol" "thanks for..." ...... just to increase their post counts (i got some of those posts too, i just want to see what the bug people talk on postpacific all about :P ). This is result of post requirement. Personally i don't like to post those meaningless post either.
As for sharing, personally i think it is stupid to post hack and and looking for hack here..... you probably thinking i am stupid and selfish to say this....but there are a lot of server owners and gm are looking through the forum. As soon as you know as you post it here, those people will know and fix it. Quite a few time, the server owner decide to wipe the server too in order to remove all hack items. In the end, not only, you don't gain anything from the bug, but it made you and other player lose everything and have to start over. Anyway, it is quite safe to say most of those so call exploit and hack here are fixed, unless you can find a new server with really noobie gms.
Also, frankly speaking, most of those who share hacks here are the same, they only share it when they pretty much bored of the game, or thinking about quitting so they just want everyone to enjoy the hack for couple of days before it is patched.
The only think probably working here is bot. There are couple of other small exploit like keeping buff when dying, clear karma, revive...are probably still working, but gm don't bother to to fix it because it doesn't do much harm to the server.
