Why not add a Player Recruitment / Services tab to Party Finder?
Especially during prime raid time when people are lfg, or lfm. I see people using duty roulette filter for recruiting for their FC, or events, or just something social. Gatherers, crafters, people offering services in game don't have a tab either.
If everyone is sick of seeing players advertisements in their PF, why not just add a specialized tab for it? Then the people who want to look can look while others can ignore it.
I think "lootmaster - order of joining" parties are a scam, so I simply filter out lootmaster and get on with my life. I think this kind of thing would work nicely for player adverts.

Just as a note - I like seeing player services/socials/FC/raid recruiting, makes the world feel alive. But, I understand others don't so let's fix it.
