The stigma surrounding selling runs is because of the people who will not bother learning to play, and instead just use RMT to pay for wins, which will then enable them to fool people (once) into believing that they can play, because they have a relic.... Though by now enough Titan runs have been sold that a relic isn't an indicator of anything, which devalues it, which annoys a lot of people who got theirs without being carried, because it makes their accomplishment meaningless.

I probably could have worded that better, but that is why people don't like people who sell Titan runs.
