Many of my answers are being deleted without leaving any comment under them or any notification.
One of them was my answer to this question. when I accidentally saw it deleted to be honest I considered it low quality and edited it completely. it is completely a new answer. I tried to respect all rules of this site. after improving it and completely renewing it, I flagged it for review and undeleting and I wrote in the flag box:
the answer was improved. please undelete.
but the result of my flag is amazing to me. this is what I saw as the result of flag:
declined - a moderator reviewed your flag, but found no evidence to support it
This result from moderators seems to me a bit unfair. I really do not understand now what is the problem of this deleted answer. please someone help me to understand what is the problem of my current version of this deleted answer to edit and improve it.
