Warning to all my friends and other people.

There is a hacker working around, "asking to vote for". Apparently the "voting site" manages to hack Your steam account and then uses account to send messages to Your friends. That happens unnoticed, the only thing that can be seen that You get Your former friends blocked. Blocking is used so that You can't see Your own conversation and remain clueless that something has got access to Your account. Play safe friends.

And try to avoid strange links and overly polite messages.

For the safety of Your own accounts, please, monitor these two links:

This one will display Your recent logins:
* https://steamproxy.net/steamhelp/en/accountdata/SteamLoginHistory

And this one will display Your friend chat history - even if hacker manages to block and delete your contacts:
