Permissions of HDD's keep randomly changing somehow only having the option "Write to Dropbox" ... I've never touched Dropbox in my life + General Privalege/Users Issues

Question

A few off things been happening recently with permission on my hard-drives and various mounted items. I've noticed this happen on and off for a good year, but gotten far worse last few days. When I right click on one of my four internal hard-drives (all OSX Journal format) as it was a few minutes ago the permissions did not even include my username name, but a new user called 'Admin' instead, and 'Staff' and 'Everyone', all of the settings were locked to the option "Write only (Drop Box). I should say I avoid any cloud hosting like the plague out of principle, not even looked at thier websites also I've even banned my computer from every single main one, for incoming and outgoing connections, by using the the Pseudo-Firewall Little Snitch. Also banned the 5+ background processes bundled with OSX that connect you to icloud.com.
I was unable to change the permissions (as write:dropbox was the only one listed for all three accounts). Since my user is an Admin I unlocked and added my local account under my login name to the list, and then I had the the option 'Read & Write' 'Read Only' and still 'Write only (Drop Box)'. Now it's giving me a few more options, like removing the admin account (even though only option is still the dropbox, same as the staff account which I can also now delete). The 'everyone' account (which I can't delete, and wouldn't've anyway, because that'd be stupid) is still however greyed out with the only option being the dropbox one.
Basically I've issues like this with all my drives on and off for months, the above is just one example of this weird kind of behaviour. So why does Drop Box keep appearing, and somehow changing all my permissions like this? That is my main question, however I'll briefly list a series of other odd things I've noted recently in the paragraph below. I just want to know if it's abnormal behaviour or totally expected.
Side-notes: a) I also have noticed strange behaviour with the hidden and locked folders and files, ie, some are locked so I cant even get permission as admin to see content of them, these folders all say 0 Byte size even though (if or when) I work my in though terminal they clearly have many files in b) many of my hidden folders give the info of being created and modified all on the date 01/01/1970 even when I add a plain document to them or something and modify them right then c) many of these folders show a new privilege for me called "Custom" (with no way of customizing or finding out what such a privilege does) and if I change it from custom to read/write/whatever, it vanishes as an option never to be seen again. d) A lot of these folders temperamentally do one of three things: The get info says it contains xx files with say 20 mb in, but when I get in it's 100% empty in explorer even with hidden files being shown, or conversely many folders hang with the loading button when 'calculating size' in-definitely only to have nothing inside, or lastly a hidden folder will says it's a got a huge file-size content (up to 3gb) on on accessing it it's blank e) Lastly some very specific folders simply don't let me in or alter any privileges at all, the only name listed is 'Admin' but it's greyed out. f) Apple > About this mac > More info > System Report > Profiles it simply says "No information found".
(This should instead be in the Maveriks forum, could a mod move it, if no one answers here, if at all possible?)
