For Kore to ban you just for flying around seems like a blatant lie, or otherwise a mistake on the host's part, unless the lag stopped after you got banned, meaning you had something to do with the lag and that you're just trying to lie about doing anything malicious
But i would need Kore to confirm whether or not the lag actually stopped after he banned you, because if it didn't, then the lag could have been from something else and that you being there doing whatever was just a coincidence
