Yes but how do they know if a plugin uses the Facebook SDK at all?
Of interest how will you know what version of the API a plugin uses? Do you have a method for searching the code of all uploaded items to determine this?
Domain is registered, DNS looks good, server is pingable, I suspect maybe the web service has crashed.
If you price the item higher then you normally get better quality users.
There are a couple of options if you search “todo”.
Specifically: Todo App & TodoMonkey
Not sure if they will suit your needs though.
What kind of tasks are you wanting to keep track of, maybe a ticketing system might work?
