Does anyone know how I can contact these members?

I have tried multiple times to contact them through the feedback, I'm aware one option is that they are choosing to ignore, however these are very old accounts most often associated with out-dated emails.

i would be interested myself to obtain some rubber mails address because the feedback doesn't works, but the owner of rubberslug doesn't reply to my mails..
