Some goals: to deter others, to extra-legally punish me personally, to pressure me into taking some kind of action that is subject to punishment, to upset others into action that is also subject to punishment, to profile me under stress, to monitor my associates as I am harassed, to watch the tactics or long term strategy, to attempt to provide comfort for these stresses (that's a weird story), and so.
So yeah, they're trying to make an example of me but it's not limited to run ins with CBP. The ongoing legal issue with a specific microblog is another example. Visiting me when I give talks is another.
There are others but I'm not comfortable discussing them at this time.
To me, it looks like you're being made an example of.
(Thanks, btw, the world needs more people willing to endure that)
