That's the thing that gets me. I get the desire to retaliate against people you feel have wronged you somehow, but as an actual strategy it seems like playing games like this with lawyers invites more trouble than it's worth. If they're trying to collect evidence, they will just send in an uninvolved third party to do it, not go themselves. But by attacking them personally, now they're going to use their legal skills to give you a headache.
