If they can seize funds coming from Neteller, why can't they

[UnderThe Gun]

If they can seize funds coming from Neteller, why can't they seize funds coming from a poker site?

At the risk of being overly alarmist, I really don't see what would stop them if they decide they want to do it.

How can anyone believe their money is safe at any poker site or e-wallet that does business with a poker site?
