“When providing us with content or posting content (in each case for publication, whether on- or off-line) using the Services, you grant the PayPal Group a non-exclusive, worldwide, perpetual, irrevocable, royalty-free, sublicensable (through multiple tiers) right to exercise any and all copyright, publicity, trademarks, database rights and intellectual property rights you have in the content, in any media known now or in the future. Further, to the fullest extent permitted under...

applicable law, you waive your moral rights and promise not to assert such rights against the PayPal Group, its sublicensees or assignees. You represent and warrant that none of the following infringe any intellectual property right: your provision of content to us, your posting of content using the Services, and the PayPal Group’s use of such content (including of works derived from it) in connection with the Services.”

We need a law student here. To me it looks pretty sketchy but it also appears that they are speaking of providing content to PayPal specifically, not simply using it to get paid for making art.
