Deleted ads

I am a bit confused. I have been selling my game calls on here for a lot of years and lately I don't know who is deleting my ads but the last two ads were deleted. The last one just last week. I am just trying to make a living and I try not to run too many ads on any one forum. I normally list 1 maybe 2 ads a month and they get deleted within a day. I don't understand the harm in my ads and I usually sell all I list so there does seen to continue to be an interest in them.

Thanks for your time.
John
