Just to updated sites that disappeared.

Buxout – closed down due to insufficient fund
Megalido – don’t know what happened to this site. The admin went quiet for a long while and suddenly the site went offline a few days ago.
Buxdotcom – site went offline without any reason given.
Foxcash – closed.

Dailyclicks – has been under maintenance for a long time

10DollarsWonder is down right now and the admin has been trying to contact the host company for days to rectify the problem. What I read in the forum, certain parts of the world are able to access the site. So, just have to wait a few days to see how it goes.
