Dearest James,
I am so sorry that you have had to experience a "troll" especially at at time of your mother's illness. I have noticed that everyone here at Susan's are very loving people and very polite. That is to the credit of everyone here. What I find remarkable here is that posts are not pre-viewed before being visible. From what I have seen here, everyone is repsectful and no posts have to be removed. I am sure that has happened, but obviously it is a rarity here.
I am a forum moderator at another site and trolls are immediately discovered and banned. We watch for the following types
Admirers,
Posers,
Trolls,
Predators,
Anyone who is identified as the above list is banned.. permanently.
HUGS
Brenda
