On my reputation tab in Math SE, I found out that I have lost 28 reputation in total from deleted questions, which is more than 20% of my total reputation. I think that this is an important issue, since when I look at other users none of them have had anywhere near the same percentage of reputation lost compared to me.
Is this normal? I feel that these reputation changes are damaging to me, since I feel my efforts are not rewarded, which makes me sometimes want to quit writing answers altogether.
Moderators — Can you please give me all the reputation back lost from deleted questions and investigate the source of the reputation changes?
To clarify, I am not asking for revenge against these users, I just want a clear and open investigation as to why this has happened and also some advice on how I can improve my answers.
EDIT: The question has been resolved; I appreciate everyone's feedback and will try to avoid poorly worded questions next time I answer.
