If WGs have an open social media account (which is after all advertising for them) then they should expect guys to message them. If they're actually a little nice to them, they may even choose to make a booking for the WG's very expensive time
.
In that context, (within reason) you take the rough with the smooth and to an extent, humour guys who message you.
Yes, there'll be timewasters and the worst ones should be gently slapped down and ultimately, can be blocked. But what's quite enlightening is the names of some of these girls: Mistress Leora, Mistress Kye - exotic Dungeon Dominatrix and Lady Atia, Domina of the Dead to name just three. They're Doms, so these kind of comments they make to guys will just make sub guys want to book them even more. They know exactly what they're doing.
To me they're just fucked-up ball-busting manhaters, to a sub guy they're goddesses and the only women who make them cum hard.
Go figure...
