If a staff member such as Dabs sent a pm to anyone asking for money and then rewarded merits to  the people that gave him money it would be an abuse.
In fact are staff members allowed to ask members for money via pm?
It would be very difficult to say no for fear of retaliation from staff.
I don't read every rule in every spot on bitcointalk,but if I was asked for money or coins from any staff member I would feel frightened to talk about it.
Look at all the names of staff that posted here. I ask any non staff person to reply what would you do if asked for coins from them?

I see a lot of legends  

actmyname
suchmoon
yahoo62278
Pamoldar
The Pharmacist
Jet Cash
philipma1957
LoyceV
Lucius


I see staff

Dabs
malevolent
Welsh

So if any of them ask a legend for coin 

the legend says yes or no

Does an honest legend fear being asked for coins from staff?   Plenty  are on the thread what would you do?

Pay up
Pm theymos
Just say no
