This is a domainer forum. Please let other domainers to say if they are offended by his actions.
Also you are accusing him of being a cybersquater without knowing all the facts. Is this how you give advice to your clients?
It's the legal section of a domainer forum, and nobody is stopping anyone else from sharing their thoughts.
Furthermore, things posted here by attorneys are not "advice to [their] clients", and cannot be. For one thing, client advice is confidential, which a forum posting cannot be. For another thing, there can be a large constellation of facts that can influence the outcome in any particular situation. In an actual counseling situation, an attorney can get to the determinative facts, which are often not considered significant by the person seeking advice. The vast majority of postings here do not include enough facts to make any reliable determination of anything, but it is worthwhile to remind folks, "Hey, you can get into real trouble if the facts aren't on your side."
And, yes, it is largely a "domainer" forum and not so much of a "developer" forum. There are all sorts of contexts in which the general notion of "making money from a celebrity name" might be a fair use, e.g.
New Kids on the Block v. News Am. Pub., Inc., 971 F.2d 302 (9th Cir. 1992).
However, for the purposes of this forum, which largely consists of participants seeking broad-based binary decisions of the type "is this okay?", and in the absence of a totality facts and potential nuances of a particular situation, you might as well flip a coin.
The other thing which is important here is that the attorneys who participate here do so on their own time and, most importantly, using their real names.
On a given question, you might get all sorts of answers from "DomainPimp", "TypoMonger" or any other number of folks who have the luxury of not being identified with the comments they post here.
It's pretty clear that quite often Eric, Brett, Enrico, Marco, and other attorneys who post here may have a different take on the usually vague kinds of questions that are posted in the forum, but whether we all agree, or whether you agree with any of us, is not a reason for telling anyone else not to share their opinion.
