I used indiegogo for a big fundraiser to go to the AVN awards in Vegas!! Someone flagged my page and all the donations I received that had porn listed as perks, were refunded.
They let me keep all other donations though- for perk of Skype with me, Snapchat, and just for no reason.
I think you can use them, just don't offer porn. Asia Akira has an indiegogo on there.
