The ban doesn't ever go away, it just becomes hidden from your profile. It's still there.

I read on the forums that there is a possibility of VAC removal after 5 years, I got VAC because my account was hacked and they were playing with cheats, I have been playing another game for 5 years, I have played 5,000 hours without any incidents, so I am asking you to consider my request to remove the VAC BAN

you misread. the vacban disappear from other users from seeing it, but you will continue seeing the ban
Example: your ban is hidden from anyone from seeing it, but there are ways of seeing it. Like i can see, by using and external website, your ban is 1930 days old. Also if you have a gameban then the bans will continue showing to everybody

I can't tell if Valve silently reduces the time for the red ban notice to disappear to 6 years or am I just seeing text illusion...
