I do understand the sentiment of wanting to protect users from themselves & far less savory individuals of ill repute that would just love to put the next world wide news virii up & down every thread they could just hoping someone clicked it..very considerate indeed..
In my short time here though..what I've been noticing affecting me directly is wanting to upload a document or image for review within the community..or view an image typically in regards to an example (error, position in game, guide photo of some sort, proof)
So my suggestion is if the ability exists..do away with the need for approval on images & document files specifically..while still choking the life out of executables..dlls & the like with regulation..
