Hi Bamboleo
WinMxWorld has a simple policy of asking folks to abide by their local laws and copyright regulations, however we have no power to enforce such a rule across the network so we stick to giving out advice and letting you make your own decisions (and face any consequences) regarding what you do or do not share.
If you do not wish anyone to be able to see your IP whilst using the WPN then a VPN would be a reasonable path to follow.
