Suggestion: extension blacklist for security reasons (user-defined) #9657
(This is a totally different motivation for issue 3369.)
If a user downloads only known files (e.g. audio/video), it is wise to block pontentially dangerous extensions, e.g. EXE, COM, BAT, LNK, VBS, (PY?), on Windows, etc.
~Less savvy users can't easily spot a ponetial threat, e.g. Matrix.avi <> Matrix.avi.exe
Background: some multimedia content is bundeled with trojans, e.g. "codec.zip" or a malware executable disguised as multinmedia file. Attached screenshot is actual video file I downloaded today.
IF a user would never download an executable via torrent, this could be so blocked by a predefined or user-defined block list, (e.g.: EXE, COM, BAT, VBS, VBE, JS, CMD, PY, CPL, DLL, LNK, SCR).
