wtf is wrong with this app?

OMG lol okay so im confused.something is wrong. i thought it was some kind of deja vu shit . so in the posts i commented, if i went back to check them another person who commented had my same name and picture. i was confused so i touched the profile and it was my own !! you know when another person comments you cant delete their comments it only says " report or hide' well for me if another person commented it appeared as if it was me same name and pic and i could press delete omg wtf ?? it happened in all the posts i commented !!
