Firstly, in my opinion, the coding forum needs more subject prefixes, those are:

[Help] - users can use this prefix if the need help with their code.
[Source] - users can use this prefix if they are releasing their application source code.
[Release] - users can use this prefix if they are releasing their application with without its source code.

Secondly, I noticed that some EXE extensions are being uploaded without a virus scan. This could be slightly harmful for the users. I'm not saying that some users might try to infect others but, let's say for example, the person's computer is infected with a spreader but that person doesn't know about it and therefore, when he/she uploads the EXE to forum it will be dangerous and will result in causing other users to get infected as well.

So, I'm suggesting that every user who uploads an EXE should also provide a virus scan with it.
The best known services is VirusTotal and Jotti.

It's pointless, A decent Crypter will make it clean.

However if they do scan virustotal those samples will be uploaded to the AV companies so it might increase the chances of it being clean.
