I can appreciate that the task is beyond one person manually undertaking it. However, when you start autoflagging bidbot customers, the logical response is for bidbots to autoflag you. This doesn't increase human society. In fact the contest is between bots using up resources intended for people to direct society with, rather than actual human engagement.
This is why I am opposed to autovotes. Were no bots involved and folks only curated manually those posts they saw and wanted to discourage from buying votes, it's likely the highest rewarded posts would get hit the most and the hardest (ignoring retaliation potential), and that over time smaller accounts would benefit more and Steem be dispersed more widely, amongst other benefits of manual curation.
Pretty sure if you either start your own flagging trail, or join those as might already exist, you'll be met with retaliation. It'd be poor business for the bidbots not to try to discourage you.
