How to Delete User Comments as a System Administrator

Question: How can I delete a user's comments on a project, task or an issue?
 

Answer:

You can't directly delete comments as an Administrator. This is done for security and audit reasons.

You can, however, use the Log in As Tool under Setup > Log in as > enter the name of the user you want to delete the comment for.

Open the desired object and you will be able to delete the comment as the user.
