I have had to ignore a couple of posters over the years, usually someone who decided to argue with me. I'll express my opinion and listen to yours but when it gets stupid I'm not wasting any more time.
One guy decided to insult me and got a perm-a-ban.
I use to have the problem of reporting members by accident all the time on The GDP…..I have found that the location of the ignore button, when I view all the guitar forums on my Android device, makes it easy to accidentally hit it if I am trying to see where a member is from or see the cool guitar they have as their avatar.
It doesn't seem to be a problem when I am using my computer.
I have hit ignore many times by accident this way.
