It's really easy to afk using teamviewer to log yoself in every 20 minutes, you dunt have to pay attention, you can get 90 90 90 in a few days

I first started afking using the android client but it's too buggy to keep open all day not to mention the battery drain.

Get 300k picking up herbs, get sub, park your guy at thugs or wizards, check every once in a while using remote vpn/TeamViewer or similar, easy easy easy, i think i got flats in like 2 weeks like this, not even afkin during the night or anything
