The first point has been discussed here before. Problems are:
- PayPal payments can be reverted, so whoever runs that site will be victim of several scams.
- It's against PayPal ToS, so they won't help fighting those scams, and they may block the account, even with funds available.
weselldoges already have solutions to those problems and it's effective.
-make max buy for different levels which goes higher and higher as u buy
Example: u start at lvl.1 with 5$ max limit per day then as u buy and buy u become lvl.2 and ur max limit now becomes 10$
This way we can avoid, instant scammers from abusing the paypal chargeback.
-add high fee (dis s ok) so even if someone chargeback, u can cover the lose.
Again, if weselldoges can do it without a problem, we can do it as well.
