"VAC was first released with Counter-Strike in 2002, during its initial release, it only banned players for 24 hours. The duration of the ban was increased over time, players were banned for 1 year and 5 years, until 2005 with the release of VAC2, any new bans became permanent. VAC2 was announced in February 2005, and began beta testing the following month. On November 17, 2006 they announced that "new [VAC] technology" had caught "over 10,000" cheating attempts in the preceding week alone."
You know that's funny that you're claiming your ban was due to the CSGO thing considering the screenshot you linked clearly shows: "First seen as banned before 2009" when the CSGO thing was 2014
