Every Friday go online and withdraw all-but-the-necessary £€$$ to your bank account (transfer wire or via card number). I do get some revenue via PayPal, and the very same day (or the next) I 'download' comes it to my bank account (connected to PayPal via card) and IMMEDIATELY is shipped to another account that has all the controls to make money (relatively) unmovable.
I perceive PayPal as my wallet. I do keep 'some' money in it but I keep the motherload away 'layers' deep.
My money flow diagram, in the back end, includes "tax", "expenses", and "vault" (alarm Scrooge McDuck) accounts.
I see PayPal as the envelope that I am given the cash in. It doesn't stay there for more than 24-48h.
Edit: someone below mentioned they do spam.. if e.g. USA authorities has alerted them about doing shady things, PayPal would also receive a gag order with it to a) freeze their $$$$ and b) gag them. If I was Niteo I would get my pencils sharpened and wake up my lawyers.
