Only TL;DR version:

Every transaction must contain a nonce so SHA256(SHA256([transaction hash] + [nonce])) < [some target dependent on tx size]. GPU miners could provide service to find tx nonces for small "fee". Spammers will be forced to spend a lot of computing power which better would be used for mining. If someone can't afford to find a nonce s/he could just include old-style fee.

Seems to be a decent solution?

Every time a block is mined, a certain amount of BTC (called the subsidy) is created out of thin air and given to the miner. The subsidy halves every four years and will reach 0 in about 130 years.

Do a search on google for

transaction spam "proof of work" site:bitcointalk.org

That would probably be easier than the forums search feature. Some of the people involved with bitpay will have a discussion earlier than that thread in 2011, and it went easily back into 2010.

The resolution usually ends up being: There are better ways.
