If a static is looking for someone to raid with and the statics progress is at O7S, so they put up that in PF in the way of "Static looking for [job] to raid, progressing in O7S, raidtimes".
Are they false advertising? They do want to play this content and they are recruiting for it - they just dont want to do it right now and more than once with the same people.

The FC-recruitment is a bit more fishy, I agree - but I also think we need an actual system that allows people to advertise and browse FCs. Something like a marketboard just for FCs, basically. We have all those fancy tags we can use for our FCs, so why cant we have a system that displays and sorts all of them?

In regards to the whole thing though... each time this topic comes up (specially when it comes to the whole selling-part), I wonder: Is this really hurting you? Is this really hurting anyone? Its not like the PF is unusable because of it (at least not on my datacenter) and seeing how this has been a thing since they introduced it, I dont think we need to worry about it getting worse and taking over at somepoint.
So... why is it bothering you? There are PF-groups you're not intrested in joining, thats all - at least to me.
