We been plagued with em
Newcomers trying to join the clubh to sell viagra and the like
Had to changeover to admin approval instead of auto registration.
Also watch out for fake eBay messages asking if goods have been sent. If you try to reply, you have to sign in and then they have your details. I had this supposedly from 'grapevinehill( 239527)'
The redirect was to a .DE domain name and that's the giveaway
Also seems most spammers are using .RU domains especially cashette.com
Admin here might want to blovk those
