Ban Risk for Online Achievement Unlocking in 2021

Hi, I am new to the forums and was wondering about the ban risk when using Horizon to unlock achievements. I have read several posts on the topic but most are fairly old at this point.

I’d like to be able to use the program to unlock online achievements for Halo 3, 4 and reach. I intend on unlocking them one at a time with maybe 15 minutes between each one depending on their difficulty. So maybe no more than 100-200 gamerscore per day.

I am wondering if a site like TrueAchievements could detect this or if I could get banned my Gamertag banned. I have also seen some posts mention the “millisecond” tags when unlocking achievements. If I understand correctly is Horizon the only achievement unlocker that inserts random millisecond unlock times?

I appreciate any advice as to how to do this without getting banned. i.e Do I leave my console online when I insert the USB containing my Gamertag? (This part confuses me a little)


As far as I know, they haven’t suspended/banned/reset since end of 2018 since it is no longer actively maintained. Haven’t seen one account affected since. So do whatever you wish.

TrueAchievements will I think mainly just detect achievements considered “unobtainable” and if a lot of achievements were unlocked at .000 milliseconds as all tools didn’t use milliseconds except Horizon more recently I think. Not sure if they care about achievements being unlocked just fast as you can randomly earn achievements fast in certain situations, not sure if repeating it would just eventually cause it to be checked. I don’t see much of a reason to care about being on their leaderboards anyway but it would probably require you to be very careful the more you do to look legit. Personally, I think it’s a waste of time to try stay on it but your opinion.
