why were my threads deleted?

[Dang94]

I posted 3 threads in parts for sale forum and they were deleted.
Why did this happen?
I'm not a vendor and if you cant advertise used parts to the nsx community, whats the use of a parts for sale forum.
Also i was told no cross threads.
All i did is post links to the parts for sale forum to notify my local Australian prime members.
This has been happening for years with no issues.
why????????????????????????????????????

Happening for years? You have been a member for less than 3 weeks.

As a new member you must panjo as you were notified. And cross posting to sale threads is not permitted.
