It's simple enough, our image upload page already has the following:
NO NUDITY ALLOWED
Do not post any images of nudity including breasts, genitalia, buttocks or characters that are wearing so little that they might as well be naked (like 1 pixel wide thongs that cover nothing up).
If you do not heed this warning it is very likely you will be banned.
There is also a link to the site terms of service on that page - there's no excuse for posting something that violates those terms, only to have it removed. You (users in general) were already told not to do it.
Simply put: If it appears on the page, it is subject to site regulations.
because the link I'm putting it´s on my property, it's like I put my phone number or my personal address, is something that is totally mine, therefore can not be applied the same analogy.
The flickr account might be your property - the imageshare pages are ours, and if you want to use them - you go by the rules we set down.
You also missed the point - we don't want people linking to any offsite item or content that we wouldn't allow here by our own rules.
The only way to get around this is not to have nudity in your Flickr Gallery in the first place (or set them to private) because Flickr links back to the user and all of their images, not individual sets.
Then perhaps that is what people will have to do for the time being. We'll see how things are setup when the remodel of the imageshare is complete and redefine the regulations on the posting/linking abilities available. Because if there is a rise in the abuse of the linking ability, then it might just come down to blocking that as well I'm afraid. Making the description areas purely text only - now I definitely don't want to see that happening, as I know a fair amount of people do like to link the mods they have used in the images within the descriptions.
If people are so determined to post nudes (full or partial) here, throw a coin in the box and get access to the supporters section. It's better than risking your account by doing something you know will get you in trouble.
