Yes it's an issue, but I will not say it done by very many people. I will say that short messages can be okay, especially when a game already have gotten a lot of feedback. But if it's only done to get people to play their own games, I don't like it.
Viewing post in "Good game bro." - PLEASE JUST STOP.
I completely agree. There's nothing wrong with a short comment, sometimes, there's not much new to add. But when it's the same comment pasted across loads of games in such a short space of time, I can't help but feel frustrated for people who just want legitimate feedback. It's like, if you want good feedback, then give good feedback in return.
