thanks for pointing this out, took me a bit to find the terms. There is this gem "obscene, pornographic, indecent, lewd, sexually suggestive, hateful, harassing, threatening, invasive of privacy or publicity rights, abusive, inflammatory, fraudulent or otherwise objectionable or harmful, including without limitation: Photos, Videos or other User Content containing nudity that would be unacceptable in a public museum where minors visit;"
Looks like they are ruining flickr right out the gate.
thankfully it is quite easy to start a flickr clone these days. buddypress with rtmedia or mediapress and bam it's done.
I was going to start podcasting with anchor fm, but reading over their terms it would be trivial for one group to to get another banned easily and vice versa, so there is no staying power / ownership of data there.
Seeing the loss of data when an account is deactivated at tumblr, fbk, gplus, or other portals, it's not worth creating a community or group within these digital sharecropping portals.
