gnahus = Bikko?

The only known social media accounts of them both were twitter. Neither of them had a public liveplay/livestream. Both are accused of cheating, but are (probably) not cheating. Bikko was especially known for their accuracy, but gnahus is also known for their crazy accuracies on aim maps (e.g kizuna music 99.44%). The most crucial fact however is, Bikko's last osu activity was in September 2016, gnahus made their account in august 2018. Bikko could have trained their high bpm aim for 2 years offline and then slowly built their skill up in gnahus' account over the years to not seem suspicious. gnahus = Bikko confirmed?
