You may've seen my topic about the reporting of game comments. Seeing how common it is for members to make short posts and seeing how you've tried to make an attempt to deal with this, I just thought of a little idea which may perhaps end this whole short posting problem. I apologise in advance if this has already been mentioned or if it's already being addressed.
Could you not perhaps code/program that section so that members are forced to write a certain number of words in order for their comment to be accepted? Something like... I dunno... a minimum of 5-6 words. If they type less, then their comment would not go through and something like a red message would appear saying that "YOU MUST TYPE IN A MINIMUM OF 6 WORDS. PLEASE EXPAND YOUR COMMENT" or something along the lines.
This way no longer could members spam with comments such as "good" "crap" "rubbish" "baaaaaaaaaaaad" and will be forced to say a bit more.
I know it's not a foolproof idea and all it might mean is that members will just post something like "I think the game is really good" which doesn't mean much but I still think it's a means of somewhat controlling these short posts.
I'm not suggesting this be done to the forums as well but just the game comments section considering the sheer number of short posts in those games. Most members seem to expand their posts very well in the forums as it is.
