Dave's dashboard

I wish to lodge a member complaint against Twitter member @amandachapel for his constant cyberbullying and other trollish behavior on Twitter, most recently towards fellow member @lizstrauss. His ad hominem attacks go well over the line of honest criticism or banter and consitute a level of abuse that violates any standards by which an online platform for community discourse judges itself. I ask Biz Stone and other fair-minded decision-makers at Twitter to asess this situation at their earliest opportunity. Thanks.
