I’ve been a couple of times around the forums, usually for a few minutes but I just saw your post. Otherwise I would have replied earlier.
I’m pretty sure we have met the same buyer, though I’m certain that he has used different names.
The first moment I saw his request (BR section) I found it a bit suspicious because it begged for people to open the file he had attached to the request. But I thought maybe his/her English just wasn’t that good so I sent an offer. He contacted me a few moments later with a message basically begging to just open the sample he’d attached. The file was apparently a .docx file so I opened it, knowing that even if it was some kind of harmful file it wouldn’t do anything because I use linux as my main OS (got windows 7 on VirtualBox for MS applications) and LibreOffice as my primary office suite. My suspicions were confirmed when I went to open the file and it wanted to be opened by LibreOffice Calc which doesn’t usually open .docx files (but .xls). When I opened it there was only some (Russian maybe) words in Cyrillic and nothing more.
If it was the same guy I hope he didn’t get to successfully send the file to you. If yes I’d do a Virus and Malware scan of your computer because macros can pose a security risk.
Now I figure that I should have, immediately, posted a warning on the forums somewhere but getting an order (a couple of minutes after he messaged me I got one) was still a big thing for me so I completely forgot. I reported him though.
