I wouldn't say don't trust all new members but rather take precautions when dealing with them. There will always be a respected member willing to act as a middleman/middlewoman.

And never forget, 'trusted' members can end up being scammers too. It's a risk we have to take. Better to be safe than sorry!

Then that "trusted" Member was never trustworthy to begin with.
That kind of Member merely waits for an opportunity to exploit another's weakness.
None of which should ever happen.
None of which has ever happened by Members who are trustworthy.
One is either trustworthy which is why others trust them or one is untrustworthy because others know them to not be worthy of trust.
Trustworthy being an action that has proven itself worthy of trust with-out fail.
Untrustworthiness being an action that has not proven itself worthy of trust even whilst attempting to hide that single point of reference.
