I understand. It is most likely an organized collaboration. I have seen similar actions elsewhere. Use of $bots ought to be shunned totally. I fear there will be more sorts of abuse on the horizon with respect to content itself. For the moment, the pool is large anough for abusers to thrive by bidding bots and knee crushers (the ones who flag opposition), but eventually, one might see a sort of content which is like click bait. It will start with 'selfies'. Enjoy and take care.
