In the scenario you describe will account B receive notifications for comments on the taxon change/flag?
Harassment has long been a suspendable offense, which would cover this scenario, but the way this is written implies that there is a separate suspendable offense of circumventing blocks, if that is the case this should be added to the community guidelines, and defined such that it is not applied too broadly. My concerns would be a scenario where A blocks B but A and B continue to interact and even discuss iNat on other social media, does B risk a suspension here despite not engaging in harassment? Or where A blocks B but still engages in discussion with B on person C’s observation, does B risk a suspension for responding to A’s comments?
Does B risk a suspension for disagreeing with A’s ID on an observation and leaving a comment explaining why?
