dont receive large multiple payments on an account that has been logged in with multiple ip's, paypal algorithm is very random. you can get a $100 hold and not get a hold on a $3000 payment it also depends on things like where the money is coming from, country, account activity, source of funds etc to get your funds call them not email if its your first hold chances are it will take longer to be available.
Does your account have a bank account attached to it? I have never had holds in 10 years of having PayPal, but I don't use for more than $1,000 per month so maybe I am just too small.
