If you put up data and remove your own datamap, it’s as good as deleted from your perspective. It means your tie with that data is gone, unless you keep versions (which is an issue for actually deleting data). So it’s not straightforward as it seems. If the data is actually truly encrypted then there should be no difference between the existence of a chunk or not. Otherwise were all in trouble
When we say not deletable we don’t mean per user, that’s cool if you remove your reference to it, we only mean network does not delete it. Like if you copy a file then delete it, it may exist in the ether somewhere, you cannot tell, but you have no reference to it any more. We should perhaps make that more clear actually in the wiki, perhaps?
[EDIT] This does mean though even if you delete your reference the network does not refund you, if it did that then it would have to keep a tie to what you have and that’s not good for security. So the network charges for Put and does not refund a delete, from a users perspective. So yes, you pay once and it’s a forever stored chunk, but the flip side is no refunds for data that cannot be tied to you. Note deletable data will be tied to you (so the network can recognise you own it), there is a risk of exposure there, unless we also do an obfuscation step as well, so again more complexity, that’s why I hesitate to rush into that for now.
