Fair enough, it happens to us all at some point. I'll edit my post to make it clear I responded to something you had not intended to say.
Are you trying to paint glam removal as some sort of saviour against reporting certain glams because people could turn them off? Look if this is the point you want to make I understand what you are getting at, but you seem to grossly overestimate the amount of people who would report this. If this was a real problem threads would be popping up all the time about seeking glam removal. And they would have been doing so for years at this point.
Just look at this thread, it's the same handful of people arguing over and over again. If you were around when Shirogane launched or when 24 mans briefly had greed only on loot rolls, you would have seen what it is like when a large number of players are outraged. Especially with Shirogane, you couldn't escape anything about it. It was even on gaming news sites, it was so bad.
Most players frankly don't give a toss about other people's glams. Why? Because it doesn't affect their personal gain in the game. That's literally it. The 24 man and Shirogane issues were essentially some manner of a loot problem (people wanted their goodies) but someone else's glam has no effect on what loot/possessions you can earn in the game.
The fact of the matter is, OP's suggestion is not only unnecessary to aid in game performance (because as I said before a pc that needs this would be unable to handle combat) it is also unnecessary to maintain harmony because for the most part no one cares how you look, as long as you don't take their loot. It doesn't make sense for SE to spend time and money making a feature that only a tiny amount of people would genuinely use.
