This to me seems more an issue of badly communicated boundaries than deliberately attempts to emotionally abuse, though?
Let's also keep in mind that a) survivors tend to be more sensitive to certain things, because we're survivors, b) internet never conveys all the aspects normally giving clue-ins about intent, c) not all people have the same communication style, or abilities, or were raised with the same linguistic & cultural background. What may seem completely rude to someone in one culture is completely polite and boundaries respecting behavior in another culture.
