I mean, to be fair... if you were to compare Futatsu scans with the /a/nonymous scans, the difference is quite jarring. But to people who don't have the raws/don't know Japanese, they honestly won't be able to tell the difference as long as it has (seeming) continuity. Would have been nice if Futatsu at least finished the field trip arc.
One thing you can consider doing is just buying one (official) Aho Girl volume every month, read a chapter every few days, and by the time you get the the current volume, 2-4 more volumes will be out. It would also scantily support the real manga author (but support them nonetheless).
