You have been throwing up the Red Flags with these threads.
Obscured links - could go anywhere, do bad things to our computers. Red Flag.
No message - just dropped that link like a bot, another Red Flag.
No involvement - Starting a disscussion and running is troll behaviour. Red Flag.
In communities I moderate/admin in, that's you out if you can't explain yourself and ammend your actions to be a bit more "community" and a lot less "bot".
This kind of promotion can backfire on you quickly if people don't like it (and should they?). It makes us feel exploited, used and ignored. And then we will dislike your videos.
