@jimfixer that's a browser feature, not an iFixit issue. We could prevent users from posting links with certain suffixes but that is easy to circumvent. Modern browsers should be scanning files before placing them on your hard drive.
If the files were being downloaded without users clicking on them I would be concerned, but for now I think this is safe behavior. Although I can see it being problematic if people hide download links inside obfuscating text.
Either way, I think we can allow this for now. If it turns into malicious behavior we can address it accordingly.
