How does Profile Rank and profile rank experience work in CS:GO

The points are distributed as follows:

• 2 points for a bomb plant. (Terrorist Only)
• 2 points if that bomb explodes. (Terrorist Only)
• 2 points for a kill.
• 1 point for an assist.
• 4 points for defusing a bomb. (Counter-Terrorist Only)
• 2 points for rescuing a hostage. (Counter-Terrorist Only)
• -1 point for killing a teammate.
• -1 point for committing suicide.

Team Collision determines whether you can walk through your team-mates or not.

If team collision is on, then your team-mates will act the same way as an enemy when you come into contact with them, namely, they will be able to block doors and the like with their body.

If team collision is off, then you will be able to freely walk through your team-mates.

This is a mostly anti griefing option, so that people can't purposely block doors to prevent their team-mates from getting out of spawn. It is also a tactical concern, as you can't stuff a bunch of players in one position if team collision is on.

Keep in mind that enemies will always have collision on.
