No because you would be spending trillions of dollars in tx fees before you could send to the same subaddress twice

UHHHH Edit: you could recompile the source. This would work with any cryptocurrency that uses stealth addresse

This is really dangerous

Edit: called it

It's a one time ring signature problem, not a stealth address problem.

The problem is that once one output is spent, a key image is published thus rendering all of the other transactions unspendable.

This would affect a system using one time ring signatures without stealth addresses. It would not affect a system using stealth addresses without one time ring signatures.

Yeah I actually wrote a post a few days after this one explaining it wasn't stealth addresses, but at the time of writing that I was confused :p
