"Account has been closed"

I haven't logged in for a few days, then today when I try to login I get a "This World of Warcraft account has been closed and is no longer available for use."
I'm assuming it's been banned based on a few other posts around here but I can't think of any particular reasons it would be. I'm only level 21, haven't bought/sold any gold(The what, 3s I have to my name should be evident enough), and have been respectful to all the other players I've met. Most of the time I've spent online for the past few times I've been online has just been to write addons and test them, but I feel like that's just part of the overall experience.
Any chance you could shed some light on this? Thanks!

Last Logged in action: I logged in after work, flew from Stormwind to Redridge Mountains, bought some Ice Cold Milk, fished up some Raw Longjaw Mud Snapper's from the lake, cooked them, ran up the mountain to the mill area, killed a spider, then logged out. Nothing sketch from what I can tell.
I was leveling with my guild from retail on the PvP realm, then they all switched to play on the PvE realm (As to be able to catch up, level and gearwise before the release of AQ). So perhaps all the time I've spent online and nothing higher than 21 may have triggered some sort of flag?
I do know I was given 1g in SW when I asked someone for help buying a wand off the AH, then I later gave another player 1g for a port to Darnassus. I spent 1g on the fishing to 225 book in BB. So my total earned currency at this point is likely 6g or so, but my currently held gold value is close to what, 3s? Total worth numbering maybe 2g in items?
I mailed every item I picked up to an alt (Verybank) to sell on the AH later on, but later found that the prices on the AH aren't very indicative of the porported rarity of the items, so I just vendored them all and sent the coins back to my main toon (Anhealer) (If I can recall, it was like 3-4g, if that). I did find a listing of Murloc Eyes on the auction house for mere copper, so I bought all below the threshold and vendored them and made a net of like 6 silver. I may have tried to name my character some odd things out of frustration, but I never -actually- created the characters and entered the world.
Past that, I tell ya I can't think of anything that could have triggered flags. For further evidence that I'm not really a toxic player (Hey, I try to give to the community when I can), and a representation of where I do spend some time, check out this thread. It's a thread I created regarding some addon's I've modified or am just posting for the public, but I've been working quite a bit on the Bagnon rework. https://forum.nostalrius.org/viewtopic.php?f=63&t=37424

-Edit-
I posted this without checking the website because it's not letting me login there, it's just constantly loading without logging me in. I changed my password and it's still prompting me with "Login failed! Bad credentials.".
-Edit2-
I'm seeing the mod addressed topic about website and game login changes, and I'm figuring somehow my account is locked out either due to this, or it's possible I tried my password too many times and broke all the things :3
-Edit3-
I micromanaged the heck out of my schedule over this week and tracked down more information to amend to the original post. I hope this is sufficient information to rectify this issue and save me from whatever embarrassment this is. My guild is outleveling me (I've been busy with work this week so my play time has been somewhat limited as-is), and well, I'd just like to be on my merry way to level 60.
