She doesn't attack and dominate the discussions here, how could she, she is among a minority who post here. Whenever she posts about whatever, she is subjected to a disguised yet pernicious attack by one poster in particular whose sole intention is to wind her up. He does this for his own personal pleasure and to see how many grinning emojis he can earn. Unfortunately, the more he gets the worse he gets. 
Perhaps, if reasonable posters here were to give him the sad face he might desist.
