Paperwork for Depositing

I don't understand what the big deal is. I have been playing at
one online casino for awhile. I am in no way a big spender, I
spend anywhere from $20.00-$100.00 a month for the last 6
months.
My credit card works fine, we get along well and now they have
changed the rules. In order to keep playing there, I must send
them a copy of my credit card, drivers license, a utility bill in
my name and my life history as to why I was born.
What I don't get is why?? My credit card is still working fine,
there have been no problems there. I have not tried to cash out
that seems impossible. All this time of letting me spend my
money did not seem like a problem, are they afraid I'm getting
close to winning or something?
There are to many casinos online to fret over this one. If they
wanted the info before I started that would have been ok, why
wait till mid stream?

Cootsoup, WHAT Casino?
They now want ID? Sometimes there
management companies ( that run the casinos)
decide they want
ID sometimes if u use credit card
Legal markets change.. like in the USA
soon no credit cards will be allowed
ALL RTGS will want ID and paperwork when u cash out

Almost NEVER will any of my advertised playtechs want
and ID and never paperwork
