I don't see what PP has to do with anything of this. They are free to provide their product to whoever. It's the operator's responsibility not to target it at forbidden jurisdictions.

Well, usually this only goes as long as your FS result is active. If you win 20 from your FS and your balance is 520 when you've finished wagering the initial bonus, you are only in the FS bonus as long as the balance is above 500.

if you take a deposit bonus and a casino offers free spins that have wagering on them, it's a trap it will mean you need to finish wagering the free spins in order to be able to finish wagering the entire bonus. some casinos tie the deposit bonus wagering with the free spins winnings. and turning for example a 20 eur deposit with D+B wagering x 30 = 1200 but the free spins winnings will mean another 30x wagering on those too thus your bonus wagering will look more like another 600 to wager, because you won 20 eur from your 100 free spins. and thus instead of 1200 eur to wager you will be doing another 600 making it a total of 1800 eur.  

Trips Casino is another one with the occassional ND cash bonuses. Even if I haven't used them much, I recently got 50 EUR to play with which I unfortunately missed out on since I had notificatiions disabled but just the other day, I got a 100 EUR no deposit bonus no strings attached but I couldn't get anywhere near the wagering req, much due to several of their slots only set to 92%. I also checked my Vulkan Vegas account a few weeks ago. I used them a lot in the past, and as I suspected there were a free 150 EUR in there (they often gave no deposit free money back when I was using them). Today I checked in again, and found 200 FS at 0.2 with a max win of 3x the won amount.

Sticking to an old favourite for the evening. 2,500 spins and despite only two notable wins it managed to pretty much break even and breaking even is always an ok outcome!
