"
so if I continue to get these spam mails to my old rosity email address it would rule that out."

erm no... flawed logic there old chap. they have that address.. so they'll keep spamming it. so, getting emails to that address only proves they are still spamming.. not that they used the Send Email option... (if they used the send email option, not using it, proves they ain't been to your profile yet...)
