Bot/Suspicious rating activity from Indonesia

It looks like there is bot or suspicious activity coming from Indonesia. A large amount of 1 ratings are coming in. It appears mostly to be impacting Korean shows with 1’s pouring in daily per show.

The screenshots are for a few of the shows impacted to highlight this and have become that way over about a week, spiking at varied rates.

The following titles (I am sure there are more) also seem to have had 1’s spammed daily for about a week with the rate of activity varying with around 5-10 1’s hitting per show daily (all from Indonesia).
