What is it?

Your Blacklist enables you to block certain users from commenting on your ads.
You can only blacklist a user who has already posted a comment on your ad.
Once you add a user to your Blacklist, they are unable to post anymore comments on any of your ads, and to contact you by PM.
Likewise, you will not be able to comment on any of their ads or PM them.

How to blacklist a user:

To blacklist someone who has commented on your ad, you need to report their comment by clicking on "report comment", and then tick the "blacklist this user" option.
The blacklisted user will be told that you have requested not to receive anymore comments from them.

Other users cannot view the list of users in your Blacklist.
