I have recently seen a post [1] where flash was embedded. I have none, so chromium (linux, Version 50.0.2661.94 (64-bit)) decided to just download the swf (then telling me it might be harmful).
I do hope there are none who have flash installed / active / no NoScript.
I think it would be nice, if there was something like an overlay of some kind to not directly embed flash once the topic loads.
