lack of time - it requires quite a lot of time if you want to start a 4chan archive
lack of money - hosting costs a lot, if you aim to keep all images
lack of knowledge - there were few small archives which died out because the admins didnt knew a thing about system administration and web management4ch.be
is no longer even private>>1187,4>4ch.be has ceased archiving as of 2016-02-27 [with no fucking reason mentioned]
the reason is that Bui simply couldn't manage anymore both fgts.jp
and take care with all of the issues which came up with them.
