Alright listen , i got a question. It may seem like a troll question to you but it's not. Back in 2018 until 2020 i've been playing on hypixel every day with a reach mod on 4 or 4.5 blocks of reach and never got banned. What i don't understand is the things u say about staff ban , because i've never seen someone getting staff banned for reach (from my experience).
Back in 2018 - 2019 it was much different. There was less staff checking people, replays didn’t exist, etc. Nowadays you have things like replays and other precautions they implemented like having people wait 72 hours before claiming rewards in ranked / tourneys.
It’s possible for someone to get LUCKY and fly under the radar being blatant, it’s just not advised to do so. In 2018 you could probably fly in ranked skywars, get masters division and not get banned.
Also when you say 2018 until 2020 there is a lot of other factors to take in. What modes did you play? Was it consistent for many hours a day? Or just a few days a week and like 1 hour.
Anyways if you aren’t lying about 4 blocking and getting away with it, congratulations but don’t recommend that here.
