Why instagram delete my comments and hashtag?

You can't delete individual hashtags, but you can delete your whole comment. Hope this helps.

I have the same problem now what should I do ..i reported this bug many times but they didn't reply or fix it.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
