1) Don't let your legal department harass your fans. Your lawyers decided what they can do legally. You decide what they should do in service of your business goals.
2..n) All of the other rules are just rule 1 again, but with recursive and geometrically increasing internet mocking added on each time you break it again.
It wasn't Hasbro's legal but an outside firm. Legal firms make money by taking actions (eg writing letters) and billing hours of "work" they have done. It is in their interest to do as much of these as possible.
I have also been threatened in the same way by lawyers working for LG. Instead of just asking me where I got the "confidential" information I posted (it was posted to usenet and some websites) they came down on me and delivered stuff to my employer claiming that me and "my accomplices at a carrier" had stolen it.
I pointed out to the lawyer that he was an unpleasant person, I would have told him or anyone else who asked where the information come from (but not provide training on how to use google) and that shooting first and then asking questions was a stupid way of operating. I was threatened with lawsuits etc, so I told him to go ahead and also to make sure that LG knew he was being an idiot on their behalf. More blustering and threats.
Then I get a call from LG with the lawyer on the line where the LG person was actually pretty decent and it was obvious they had no idea what the lawyer was doing. I told them that if they apologised then I'd happily tell them exactly what I would have told them if they had just asked nicely in the first place and delete the information (which of course could still be readily found all over using Google).
So they said they would and I kept up my end of the deal. They then proceeded to not actually apologise.
(I ran an extremely popular site for a particular LG cell phone helping many fans. The "confidential" information was what the changes were in each firmware update. It was rather boring stuff but there were fairly frequent updates so naturally people wanted to know what the changes were each time.)
TLDR: So I have learned my lesson. Lawyers are worthless scum and you should never believe a word they say. You cannot expect them to behave within the bounds of human decency. And they get to bill someone for every hour they act like pricks.
I learned that myself when I was contacted by a trademark attorney about a potential violation of a trademark of a company that we were friends and partners with. I called the company directly, got the CEO on the line and asked WTF. He didn't even remember the law firm. They had used it to file a trademark years earlier.
The law firm filed with ICANN and took a ___domain name that we had that I had freely offered to our partners whenever they were ready to use it. I tried to transfer the ___domain to the partner but the lawyer had already taken it, and held it hostage for the payment of the legal bill! They still have it.
You have to be very clear with lawyers where their work ends or they'll make-work you to get a few more hours and make you look like an ass in the process.
