Why should have the Pandaplacer announcement be removed? Pandaplacer was discussed on this thread in Reply #687 on: June 13, 2023, 04:10:29 pm, that is why we submitted additional details as they became available to the benefit of the community and everyone interested in small cheap machines.
I suspect your posts were removed because you posted the exact same thing under multiple topics, and that is generally not allowed on forums.
You have not been banned (yet...), so I suggest you take it easy and don't pick a fight with other users or competitors.
Maybe re submit your single announcement post and leave it at that until any questions are asked or interest is shown.
