Question Vetting Discrete Message (DMs) Requests

[PussPekr]

After my first Review of an MPA I received a DM from a member asking what service I had rec'd . Also wanting to share his experience with same MPA but telling and fishing for high mileage info on other MPAs at that spa.
Things like BBFSCIP, BBFSCIM, Now I am not naive, I know this occurs but it is not my thing. I don't mind getting this info but I wonder what their motive is for putting this info out there. If I believe I might not visit spa or girl again.

QUESTIONS : How do you vet what information, how much information, and who to share info with?

I played along with a member who joined in July of 2020. Has 113 messages. Maybe I minor review among them.
I vetted his messages.
Most of his messages are questions. When are you open? what service did you get? etc etc. Others are one line comments nothing of value.

Later I told this entity (member)what I thought of his DM.
Being new in sharing my vast experience on this board I am wary of "all kinds of players". From LE to known and reputable reviewers to "Father Mulcahey"

Does anyone have any thoughts on this topic ? HELP ME OUT.
Should I respond or ignore?
Should I share with even reputable member?
