My own experience in other MMOs is, that addons telling you DPS don't lead to much more harrassment than usual, but to improvement in midcore and hardcore content.
Some people feel the need to harrass others and they will always find a reason, DPS is only one of them, I have seen people being harrassed for hundreds of reasons (mostly by people who run 10 dungeons a day but haven't even completed T13 and need to prove something to themselves).

Only way to give PS3/4 DPS meter is, when SE decides to put it into the game client. That way also PC players could finally use it without the constant fear of getting banned and people could finally discuss job performance and suggestions properly.
IMO there are way more pros than cons for official DPS meter. People, who like to turn off their brain in dungeons and click 2 skills are afraid of it, but let me tell you one thing, people can notice that even without DPS meters and most probably in your every dungeon run there is someone with DPS meter, they just don't care, because they know what they are going into every time they enter roulette via DF.
