It occurs to me we should enforce some of our trademarks, because rampant infringement of Wikipedia's trademarks, and Wikimedia's trademarks in general is occurring. If we don't enforce our trademarks IIRC, we will eventually lose the ability to enforce them forever.
For example: WikipediaClassAction.org is violating our trademark and copyright. Wikipedi.org, wikicommons.org, etc. are candidates for trademark infringement. I am not a lawyer, but it occurs to me that we apparently abhor being on the defending side of lawsuits so much, we abhor being the plaintiff.
There are several reasons why we should do this soon (ie. issue takedown notices for infringement for these sites):
1. It would establish our authoritative presence in the legal arena, while being relatively easy cases. 2. It would show that we are determined to be accountable, ie. it would dissuade possible malicious vandals, or make them think twice, while not discouraging new users. 3. Following this logic, it shows that just because it is Wikipedia, it doesn't mean we're weak or helpless, or can't eventually use the long arm of the law to find those who try to sabotage the encyclopedia. 4. Imagine what the consequences could be if someone redirected a typosquatting site targeting the Wikipedia audience - to a porn site. 5. The GFDL is being enforced in the same manner: it doesn't compromise our "free as in freedom/information wants to be free" philosophy whatsoever. 6. There's a large chance this will help unite the community in external action.
We would discourage new users only very minimally, and might give us some controversy, but that's only because of the misconception that open source => weak and vulnerable.
On the other hand, people have raised up suggestions that we also have a large case against Willy on Wheels and Wikipedia is Communism.
Of course, I do not seem to know why we don't do this already. Thoughts?
