How to abide to the law while rejecting threats
According to Spanish law
web (emphasis mine):
Information intermediary suppliers:
Do not have an obligation to supervise the contents they host, transmit, or classify in a link directory, but must collaborate with public authorities when required to interrupt an IT service or take a content down.
They are not, in principle, responsible for alien content they host, transmit, or give access to, but could incur in responsibility if they take an active participation in its ellaboration or, if knowing of a particular material being being illegal, do not act swiftly to take it down or prevent access to it.
So if “someone” send you threatening messages, requiring take down, etc, etc. you have NO obligation to do it. Such request must come from a public authority (like a judge), and the responsibility derives from a content being ILLEGAL (which, again, can only be determined by a judge).
STAND UP FOR OUR RIGHTS!
And, remember: don’t feed the troll 😉
