Coetg.com - Are they legit?

I was sent a message through ebay, promoting this site... Does anyone know if they're trustworthy?

They are listed on both firetrust and watchdog scam alert sites as being a scam site.

Too ebay would not have sent a message promoting any site. I would say that it's spoof and phishing message. I would suggest going to ebay's security center and reporting the message there..

Sorry, what I meant was that it was sent by other users. I'll take your advice and use the Security Centre, though.

If it was sent through ebays messaging system even though by another member it is not allowed..

It's likely they're scammers. You will get a message like this through ebay at leasst once a day. Just ignore them.
