PTPA. A friend of mine just pm me because someone in his friends list in steam just asking a favor about supporting their CS team (he said something like about Team Boosting Rep) and give the link (link in the image). When I check the link, it just registered 2 days ago and cannot be found in normal search in google/duckduckgo search engine. So, I told my friend that he should not click the link and unfriend that person.
I really don't know if Team Boost Rep in CS exist. I really think this is a scam.
