No posts have been deleted. Generally nothing is deleted except in special circumstances - spam, at users' request etc. I'm not sure how to help really. I see you have only posted 3 posts, being this thread. Do you have another user account here, and is possible you used that account? Not too long ago I went through all the forum posts and moved some threads to more appropriate topics. All of the arduino code/posts (including ESP8266/32) are in the 'Arduino Code' forum.
