The only obvious problem with the �ignore� function is that you want the ignored person to know that they are being ignored. Often silence speaks volumes, so it is much better to not get involved or just go through the motions of ignoring, rather than actually selecting an �ignore� function.
Personally speaking I don�t ignore particular users. More often I ignore certain threads. Sometimes though, �certain� users post an irrelevant or abusive point within a thread, which the AB Editor deigns to keep, so I just ignore it as if I haven�t read it or it has no affect on me whatsoever. Usually I couldn�t give two shrivelled monkey nuts either way.
Use of the site just requires some self control and a laissez-fair mind set. Rather than get worked up, take a deep breath, think of Lauren Cooper (Catherine Tate) and mouth the word: whatever.
