hmmm. I see. my buttons are different than your screenshot. mine has...

reply button/ multiquote this message button/ a quick reply button/ thanks button /hugs button. (I dont know how to make a screen shot sorry)

most times I use the reply, this way it automatically tells me when I am on a persons ignore list and also when not on ignore list it automatically quotes the post I am replying to. sometimes I do use the large quick reply box at the bottom of the whole thread, when I do this is does not tell me if I am on a persons ignore list.

since your buttons are different maybe someone else with the same format that you are using can help you. otherwise my other suggestion is experiment with what you do have and maybe you will hit on the right way that will allow you to know when you are on someones ignore list.

sorry I couldnt be of more help on this.
