I'm not very knowledgeable about the other 2 payment options, but from personal experience I've just found that when you use PayPal, you just need to avoid mentioning anything related to cryptocurrencies, and just send all payments as friends or family - this sucks because if you get scammed, there's no real way for you to get your money back (because if you mention cryptocurrency, they will basically just ignore your claim). There's also limits to size of transactions which may cause your account to be limited, personally, I cap myself at 500 USD per paypal transaction, and I've never had issues.
For skrill and neteller, from the look of this thread, I wouldn't recommend. Paypal definitely seems to be the popular option here.
I agree with you for PayPal, from what I've seen theres a 1,000 USD limit on transactions (so after you have more then 1,000 in your paypal balance, your account gets locked and you need to have ID before your able to use the account again), pretty easy to avoid, just make sure you spend/withdraw money from your PayPal.
Neteller is a no for me. Accounts randomally getting restricted, transactions getting stuck, shitty support - not sure why anyone would ever use that service.
Skrill, no idea, haven't used it before.
