Warning: the text below can be disturbing to the readers mind!!! Proceed with care and if you are not up to such then leave and never return to this specific part of this posting.
External influenced conversation lifetime: patience of the moderator, cleaning obsolete posts in database, an of course total POTN lifetime, limited by lifetime/ interest by Pekka or successors or availability of currency or other means of payment/exchange to keep POTN a-life.
Mean threats, limiting the lifetime of posting and ability to post due to: total black-out, ISIS not liking the Nude section of POTN repeating a "Charlie Hebdo", human population being replaced by robots/AI, invasion terrestrial or non terrestrial, conventional and/or nuclear war, total lifetime of humanity and in case of total automation lifetime earth. Availability electricity is guaranteed by fusion reactors on the Moon with an reservation on a celestial collision.
Question to Pekka, are there plans to expand POTN outside the earth because then I have take more possibilities in account to answer all the possible questions in up front.
Enough bla bla and I am going to get some more sleep that I missed earlier.
