LFG - 50-70% WTS. you report them, in few minutes you see tons of WTS more.
WTS with gold, WTS with 3rd party links (guess RMT).
It looks like half the ppl when making to some level start WTSing everything.
Wow is work? Or what is happening?
Selling boosts is legal, although a horrible aspect of the game which Blizzard doesn’t want to sanction due to huge number of people selling, they don’t want to hurt their income.
Since buying gold for real money then buying boost for that gold is simply more efficient. Demand for boosts went trough the roof so many players just bank on it.
You can put the boosters on ignore or get yourself an addon that filters out WTS stuff. Both solutions will give you much easier time if you look for real groups.
There is also the “report for advertisement” feature which seemingly does not do anything. The boosting groups appear in your group finder very quickly after you report them away.
