Its likely important to maintain a minimum presence of legit posting, that said I wouldn't engage the bashers at all. Definitely don't respond to them.

One interesting "glitch" that ihub produced yesterday for me was I was curious what the appearance of ignoring a member was (totally removed traces or <This message is blocked, click HERE to see it> etc.). Anyways I selected one of those new faces to ignore and ihub blocked about 6 of those new faces... I couldn't get it to repeat that after the first time but I did find it suspicious considering folks have questioned how many actual bodies are behind the various alias's...
