The idea of ignoring a member is completely personal and it really doesn't matter what others think if you do or do not ignore another member.
Each member here, when your account was created, agreed to the Community Guidelines of this site. Found here -

Each member is bound by those guidelines. Psych Central was created to give individuals a safe place to land and discuss their mental health issues. No one here is obligated to anyone else except within the guidelines. In other words, if what you have to say to another member is not supportive and not respectful, then it's probably against guidelines.
At this time I will be closing this thread as threads like this usually turn out being unsupportive (as this one has). Discussing other members publicly is against guidelines whether specifically or generally.
With Care,
