Is it my imagination, or is the majority of dead posts I run across (several dozen over the past several months) hosted on MEGA? I've only encountered one or two on Mediafire.
.. @gts6 .. i did ask the same question once and the reply was that
"m'fire is one of the more reliable hosts and we don't want to attract any undue attention to it.. though it is not listed, it is ok to use m'fire links"
Another issue with Mega, to make sure that all accounts are logged every 6 months (or whatever period) to avoid the accounts getting deleted. This is the case if you have multiple accounts.
