People can always chargeback a payment, regardless of what method is used. Unless they're sending from their own balance, it'll be very easy to dispute a payment. Giving paypal reviews a quick read would tell you this.
I have an account that's got all champions (except taliyah, or maybe not) and 40k-47k IP with 7 rune pages and over 300 skins.
Send me a private message if you're interested.
