Theres nothing wrong with buying clears. I want to see content, I don't want to grind gear. Doesn't affect you in any way. If they brag, just ignore them. Its not a witchhunt though, if you let them bother you or rant about it you're just feeding a troll.

Think about it this way, the people that can clear it (even carrying someone) gets gil, the person that wants for whatever reason to buy a clear gets their clear. A definite win-win. No need to attach meaning to everything someone does. Don't judge.
