Thank you, yes, it worked on my second attempt now. Are there any more free offers to test this out (not begging, but if there is, I'd love to look at a couple of transactions)?

Another question, is there a way to use the service to look at a set of txs and auto compare for similar fingreprint/pattern/behaviour as a way of marking them as part of the same cluster?

Also, what's your false positive rate at the moment?
