Phase, I have partied with smaller parties and the most abnormal setups. In fact, I often find them quite more enjoyable. But I also know that I've been invited to parties, we went out, we were doing good, someone left, and they have invited people who I normally wouldn't want in a party. I'm not going to leave and spend 3 more hours waiting for an invite when the rest of the party is just fine. And when I say someone who I normally wouldn't invite, it could just be a plain old bad player who isn't good at their job.
I have nothing wrong with people who don't spend millions upon millions on their equipment. As long as you try to keep your character respectable, I'm a happy camper. Not everyone has hours upon hours to dedicate to farming for the best. But that's just my point. Sometimes, no matter how flexible you are, you end up in a party with someone you don't like or is suspected, with no proof of doing something harmful to the server. To me, it's rather childish to leave a party because so and so is accused of buying gil when the rest of the party has been doing well.
Sometimes the witch hunts is what drives people to do these things. If you are constantly being accused of buying gil when you are busting your butt to farm, and your rep goes into the toilet, why not just turn to buying gil instead of wasting hourst to farm? Everyone already thinks you do anyway.
As for the sellers as long as there is a market, they are going to be in our world trying to advance in the game to make more money. They are going to get there with or without our help. I'm not saying it's ok to help them. But for people who do end up getting in an exp party with them and not wanting to leave because the rest of the party is good, I don't think we should crucify them either. Not to mention with all of the accusations flying around of who is and who isn't a buyer/seller, it sometimes makes it hard to know what's the truth.
Unfortunately, without actual proof, se's hands are somewhat tied when it comes to getting these people off of our server. Usually, you have a better shot at getting them off by reporting them when they mpk or whatever. I know in a lot of cases nothing is done or maybe a verbal warning. But as long as we don't stoop to their level and make everything worse and keep reporting them when they do crap like mpking, we may be able to at least ease the pain for the people there just to have fun.
Maybe my other post didn't phrase my thoughts well. I just get sick of seeing everyone at each other's throats over the same issue over and over. We complain about these people ruining our experience in game, then we end up fighting with other people in the same boat and it just makes the whole experience worse.
