Do it for the lulz/morons, to be honest. You didn't do it to prove that you're right. You argued with people because you
knew they were wrong. You could have been just as wrong, you could have been the pot calling the kettle black, but then so fucking what? The kettle is bloody black. My mantra is sticking to the truth, and if that means calling idiots idiots, then who's to say I shouldn't? Maybe you're at the point where you grew weary of the same old arguments, maybe I'm the immature brat that refuses to let it go; but you know what? I'm fine with it. I will continue calling idiots idiots, and I don't think you should stop because a couple of buffoons broke their sweat trying to reason with you.
logging into a bt tracker account every few days, posting maybe once or twice in the forums and snagging a couple of small torrents, which is pretty much what my private bittorent tracker memberships have become
Which is what should be done, to be blunt. If a tracker truly believes that it's bleeding because there's not enough "8/10, awesome movie" posts on it, then the staff and the active members are all bloody idiots. I've finally given up on the whole community participation thing on trackers, most of my posts have been reduced to a trolling farce, and I've generally conceded defeat, considering it seems like anyone I talk to is just out of high school, and has just as much understanding over any concept that's not related to pretimes as a dung-beetle has towards Japanese.
Being an active part of forums/irc/competitions is a waste of time, and although I do admit to being part of that crap before, I've found out I was just wearing myself down faster than I would otherwise.
No one should look for a community in a private tracker, and that's what I've finally found out, so you know what, if you feel like you're a terrible member by doing the bare minimum; take my advice. I'm someone who's done the opposite and is now willing to flip the switch and turn into you.
