[I do agree this is a very safe way to get people identify their own addresses but my original idea was to have a way to also tag other addresses. Scammers will not give their own addresses a scammer tag. Many very public addresses scream to get indexed somehow but their owners won't host such a file. Yet I'm sure people would pay to enter addresses in some index.
I see what you mean. The foundations for an address tagging system are in now.


So just a good system is needed for users to submit their own tags. Either:
- Directly on the block explorer pages, I'm not quite what this would look like since address pages are quite cluttered anyway. Maybe just double click in place to edit an address.
- A new page specifically for submitting, up / down voting and reporting spam tags.
- Have an address that you can send a transaction to which contains a tag embedded within one of the scripts. This is abusing the blockchain a bit though.
- json file which you can upload to a webserver which will blockchain will index. Downside is you can't tag other people's addresses.
I'm not sure which would be best, what do you think?
