that imports as
https://blockchain.info/address/1MtR9nBGfWBLY23q4dRGRjjzBBiEdxRmC3

if they are not valid addresses then that is a fatal flaw in the blockchain because it's showing as a valid address and you could send coins there

If you edit the address it comes back as checksum not valid, so it clearly does check the addresses and says that this one is valid. If it's not then blockchain is fucked

eg:
https://blockchain.info/address/1MtR9nBGfWBLY23q4dRGRjjzBBiEdxRmC2 is not valid (change 3 to 2 at end)

This is not true, there are extremely large number of BTC address that no private key hashes to. If private key (WIF) checksum is wrong, no decent wallet should import it. For instance look at this BTC address:
https://blockchain.info/address/1BitcoinEaterAddressDontSendf59kuE
You can send money to it, but you can never retrieve coins from it. There are thousands of transactions like that in the blockchain.

that's still a valid address though isnt it? it's just that no one knows the priv key. That's different, here blockchain is importing a "private key" and giving you what it says is a valid address, if you edit the address it says checksum isn't valid, so that website clearly thinks that an address is valid that the other guys are saying is not, which seems to be a big flaw in blockchain.info.
It's saying https://blockchain.info/address/1MtR9nBGfWBLY23q4dRGRjjzBBiEdxRmC3 is a valid address, and the guys here are saying it isn't
