Anything which is more important for you now is to find that user who is consistently reporting your posts.
There is absolutely no need to go after whoever is reporting posts, it's also not possible to find out as such information is only available to mods and staffs. The important thing is to maintain your post quality and only contribute naturally when you have something to add. Your posts would not be deleted simply cause they were reported, the mods need to agree with the comment in the report to take action.
