Just because it is a Hassle to have to explain to someone how to zip a file and upload to a hosting site. Everyone is aware it could be malicious, welcome to the internet, you know the risk involved and if you take certain precautions such as I do its harmless. This is a site where people who are well educated and informed about computers help fix others problems, I doubt they will have an issue themselves.
The reason why is because one of the most effective tools to have is debugging .dmp files and crash files/minidumps. It would be so much easier to just upload one and grab it quickly so I can further help the OP faster and more efficiently.
And if you get a Virus from a file like that shame on you, You should always have enough protection to stop something like that, and at least prescan the folders
