This feels very much like the quick and dirty way of solving problems that we used to see from steemit inc back in the day. I remember their brutal rate-limit implementation killing many asyncsteem (python 2 lib) cron scripts and some scripts.

The L1 has pretty much solved problems like this with this with the RC system, that doesn't have devs chasing after the capricious whims of platform devs.

Have you considered implementing something akin to the L1 RC system in engine?
