Pests, they are seemingly everywhere even in our little haven of WordPress, I thought as many that you could do no more than tolerate them. I have had one commenter I have asked to stop for about a month now to no avail, I have tried polite emails, not posting their comments, even a polite Facebook message nothing worked, as a matter of fact this commenter was so arrogant they basically told me if I posted anything in public calling them on it I could get into legal trouble. I am not sure how , or what type of trouble this could be but this commenter claimed to be a legal professional so I sought other measures I could use.
Ah but inspiration can offer us hope still. So if you have for example a commenter who has become a pest and a polite please stop commenting on my blog ect does not suit them here is an option you may find handy.
If you have a public blog it is perfectly legal for them to visit and comment if you have comments enabled which the majority of us do. So what options do we have if we want an open blog and do not wish to have to monitor every flippin comment and we have a pesky commenter who will not go away, well WordPress does offer an option just for this every purpose.
Simply enter your control panel for each blog and select the settings tab and then discussion menu and from there drop down till you see the area marked black list, take the info from their comments such as IP Address, URL, email, their name, blog name, and any other info listed about them and copy and paste it into this box, and do not forget to click save changes down below.
Now let them comment all they wish, it will simply drop their pesky comments into the spam folder and you need not ever see them! As you can imagine there is always a catch but this one is not that bad, they could change their info and therefore not be on your black list but then you have a legal leg to stand on in many cases because now this could be considered harassment in some states, so check your local, states laws on this matter if the issue persists.
I prefer to be polite and simply ask a person to stop this behaviour or that, but some people are to stuck on themselves to behave nicely and think they can do as they please regardless of how their actions affect another, shame , shame on them. But as they say not all roses smell the same and some are just for the byrds!
