You have marked your response "private", which means that the only people who can see your reply are (a) the original poster (in this case, you), and (b) moderators and admins (me). If you want anyone to see your reply, you shouldn't make it "private".
You should deactivate all your plugins to rule out a conflict (sometimes with an updated to WordPress, there are plugins which haven't been updated, and don't work).
I'm just a volunteer moderator, so I don't have the ability to ban users, but I did mark all their replies as spam, and that got rid of them.
Thanks for the Mother's Day wishes
If you don't know much about coding, there are a number of places to get started.
Tonya Monk's Know the Code and
Carrie Dils' series on Lynda.com
would be great places to start.
