📝 Original message:This should not be enforced by default. There are some use cases where
address re-use is justified (a donation address spread on multiple
static pages or even printed on papers/books?). For example, I offer
some services on the internet for free, and I only have a bitcoin
address for donations which is posted everywhere. Obviously this could
possibly harm privacy, but not everyone who uses bitcoin wants to keep
all transactions private. To the contrary, there are accounting cases
when you need to archive all keys, hashes of transactions and
everything (for example when using btc inside a company which is
required by law to keep accounting registries).

I know it's not recommended to use the same pubkey more than once, but
the protocol was not designed this way. Enforcing something as
described in this topic will undermine an user's rights to re-use his
addresses, if a certain situation requires it.
