I tried to provide a solution for this by mapping emails to an address
www.coinbook.meWhy would you post this? Here is a short list of obvious problems:
1. Everything mentioned in this thread so far about DNS models, which presumably you read since you're posting here.
2. The obvious security implications of people trusting you with a giant database of email addresses, and sending these to you, without HTTPS.
3. The obvious security implications of you publishing bitcoin addresses from your database, without HTTPS.
4. Only supports one bitcoin address per transaction; every additional one "succeeds" according to site but does not show up in the lookup.
5. You do not validate checksums. I was not only able to register bad bitcoin addresses, but even "addresses" which had various special characters and looked nothing like a bitcoin address.
6. Removing addresses does not work. The link in the confirmation email 404's.
I appreciate you are just trying to accumulate email addresses for whatever nefarious purpose, but this is inexcusably sloppy.
While you do have some point on HTTPS, you point 3 is stupid. There is no implications showing your "public" btc address.
