Happy to answer. No we've never been contacted by law enforcement, as the canary indicates.

Things have been removed from external request in the past, only maybe 5 removal instances in the last 3.5 years, and it's been over a year since we had an instance of something needing to be removed (typically as requested by the server company). The posts asked to be removed were basically all from copyright violation takedown requests. Pretty minor stuff in the scope of things, but if the takedown requests ever get out of hand we're ready to change server companies again if necessary, as we've already had to do 3 times over the last 3.5 years to keep saidit running.
