The main problem with Haro is the almost complete lack of acknowledgment.
Those seeking (free) help can at least hit the reply button and type THANK YOU or paste in a pre-written acknowledgment. If the material is used, the user should notify the person who took the time to write and submit, obviously.
Claiming one is too busy to reply while fully expecting contributors to spend a great deal of THEIR time to help a reporter out, is entitled and selfish. It’s just good manners and common sense. I wrote to HARO asking them to address this matter to their reporter members but received no reply from them.
