Hello everyone, there seems to be there may be phishing bot going around this group and other groups. Here is an example of what it will send to you:

4:23 PM - Another TF2 Raffle Group: Hello! Thank you for adding me!

4:23 PM - Another TF2 Raffle Group: I am a bot Public http://steamproxy.com/groups/TFTRGCommunity
you have been randomly selected, you are the winer of Villain's Veil Strange unusual

In order to get the keys enter the code
4:23 PM - Another TF2 Raffle Group: indicated in the picture [PHISHING LINK REMOVED]
4:23 PM - Another TF2 Raffle Group: If no action was taken another winner will be drawn ( you have 3 minutes)

This link is NOT legitimate.

If you have clicked the link, I highly suggest changing your password and de-authorizing all other computers. Make sure your steam password is different from your email passwords and change email passwords if you feel like it is needed.
