Dishonest

Take care, bud.

Wouldn't classify myself as a 'dedicated forum user' as much as I would a secret adviser. 

Should've always been a rule; there's no possible way to fully moderate it other than to treat it like other forms of advertising.
Plenty of people have used their YT channels to support other servers along with the current server they are playing on which in turn creates this dynamic where players are looking up your channel and being drawn to your off-topic content (other servers). 

Where as posting your videos in the video section of the forum posts an embedded link to the video and any further clicking from the consumer is at their own discretion, meaning if they truly are interested in watching more videos of the user they're watching, then they physically have to click past the embedded link and begin surfing the channel, where as the current system, players are advertising their channel that could potentially have 1 Alora video, and 50 Ikov videos (using an old closed server as an example) which in turn may draw the viewer toward Ikov.
