I would go further to say that whoever told you that people won't look your direction if you are not affiliated with a PRO (Performing Rights Organization - ASCAP BMI or SESAC) they are full of baloney (balogna).
All that means is that YOU get paid when your music is performed in public. The promoters don't. The managers don't (unless they own all or some of your publishing) so what would be their motivation to require you to be affiliated with one of the aforementioned societies? It really is there to benefit you.
I could maybe see that publishers want you to be affiliated.
In the case of ASCAP, you have to have had something performed in public to be a full fledged member, so maybe to some that would be an indication that you have enough talent to be considered. But then, I could go down to a coffee house and sing about the size of my dong, and there you go - I have written something and performed it in public - doesn't mean I have talent. BMI is not the same as far as requirements to join (I think) The only other thing I can think of is that being affiliated also may show some business savvy on your part.
But don't get me wrong, if you have written and copyrighted material that is being performed in public - you should sign up.
Don't worry about ASCAP asking for your SSN - ASCAP is older than social security - that should prove some legitimacy.
