I am not sure if you have already try it out but
try to get in touch with the @hivewatchers if you think they got you blacklisted for no apparent reason
Here is their discord channel https://discord.gg/7FkETjJ

I hope you guys get this thing figured out. I am not sure if they have an automated bot that automatically blacklists posts with certain criteria but I didn't notice some kind of offence on your posts. I follow you since 2016 if I am not mistaken and never noticed an offence. I am really surprised.

Edit: I just logged in fro Peakd app and it is not censored.
