I'm sorry, Mia is not a saint. Even saints get criticised. Don't expect to appear perfect to everyone. You have gotten a bunch of positive karma, did you create a thread to ask why you've got positive karma? I don't think creating a thread is the best approach you should take here. Maybe it's because of the telegram notifier you use. Sometimes my karma adds and sometimes it's stagnant as if it's reducing, but I can't actually track it because I don't use a notifier and I don't care.
Personally, I don't like giving negative karma to anyone, except plagiarists and spammers. In some cases, I have intended giving +ve karma but mistakenly clicked -ve karma. But in such situations I'll click the + again to balance. This might also be what happened to you.
I have given you +1, don't let a -ve karma bother you, it's part of the system.
