Buy Solaris message

Got a message from a random in game last night about purchasing Solaris from a website, mmorpg gold .com (it was purple message even though I wasn’t friends with them?)

Never seen it before, so seems to correlate with this sudden discovery of people duping their Solaris at the bank. Someone else suggested they’d be money laundering?

The person who sent it also had a name like ejlkjdhsj

I’m new to MMOs though and I assume this basically happens with every game. Anyone else get a message like that?
