This guy isn't spamming transactions on the bitcoin network.  He is changing transactions just enough to cause a spam effect but not enough to have them rejected by the other nodes.  I don't think that will work on bitshares.  My concern is regarding the fee for proposing transactions.  The way I understand our multisig is that you can propose a multisig transaction and broadcast it.  It is then up to the other key owners to sign that transaction so it can be included in a block.  I was wondering if this is a possible attack vector that would allow someone to Spain without having to pay fees.

Very interesting.  Could something similar be done in bts by spamming proposed multisig transactions or is there a fee involved with proposing a transaction?  I'm assuming maleability doesn't apply to our transactions in the same way.

I welcome anyone attempting to spam bitshares.  Thanks for the transaction fees. ;)

Interesting read. He says it had no costs, but even if it had some, my question is, this time Maclin decided to do it, what if next time we have 10 Maclins doing it? I'm not sure if it's as easy to do as he makes it seem, probably not, but if it is even remotely feasible to do this, what if someone malicious decides to keep going for a long, long while?
