Please DM me to explain removing my posts

Dear Moderator:

Hi - I am not particularly upset about my posts being removed (a kind reply answered my fundamental question). But I had read over the posting guidelines:

https://forum.audiogon.com/pages/guidelines

I am unsure, based on this, as to why my posts were removed. It might be helpful to provide either a dm explanation or even a post explaining to the community as to why a particular post was removed. I would like to understand parameters beyond what is on the above web page.

thank you, Mike
