how to delete account on brainly plse

Answer 1

You cannot delete an account yourself but you can ask a moderator to do so
If you even uninstall Brainly then also your account will exist
So only way to do so is to ask a moderator
Well another easy but inconvenient way is that keep on spamming and moderators will themselves delete your account

Answer 2

you can't delete your account by yourself so contact to the moderators
