I'm aware that I can follow hashtags but those are not bound to specific contacts. I.e. I might want to follow everything @hoergen
posts about #cats
, but not what *everyone* is writing about #cats
Or take my nsfw collection on G+, while being a collection of sexy images, I avoided posting anything outright pornographic, and avoided nudity as much as possible. So while NSFW, it was somewhat "safe". I'm sure my followers don't want to simply follow the #NSFW
Another thing i thought about is creating specific hashtags, e.g. #patmax17NSFW
but it's a clumsy workaround...
