I'd guess "officially" it's up to the individual instance but, personally, I'll be blocking them... life's to freakin' short for that nonsense and honestly it's why I'm getting a little tired of the "other" site.
The social aspect of social media has been getting lost in the urge to broadcast and market every idle thought.
Let's all talk instead :)
@Emperyan So glad to hear someone else feels that way. I honestly am exhausted by the "here's how to monetize your personal brand" crowd, but then I remember when I saw my first corporate website at 15 or 16 and was bummed out about the end of the internet. It was for Juicyfruit, which I've thus never purchased.
