Bnet Accounts "locked" unusual change in its access pattern

So I just had 2 of my accounts "locked"

Blizzard has locked the Battle.net account <email> due to an unusual change in its access pattern.

Merely locked, all I had to do was change the PW, but is this any reason for concern?

The accounts are fresh, I RAF'd them with my main, used dungeon buddy and questing bot. (my main has a long long history of many RAF accounts, both legit and for gametime). So no reason for concern there.
Also had previous accounts RAF linked to my main, had no problems there either. Accounts are nearly level 90.

My main account didnt get this lock, anyone have a clue bout this?

 

From my recent experience - Just started leveling 6 new toons it will always happen if you log in from a different location (different IP) Did you log in to game maybe from work or from school or maybe from friends hous or used your laptop in a coffee shop ? Your accounts been locked has got nothing to do with botting or Rafing - I think. It happened a lot of times to me when I was playing from home and then switched to work computer.

Regards

 

I don't recall logging in from a different location, only thing I've used was Teamviewer to monitor my bots, aside from that the only thing that occured... was my ISP died for a couple of hours.
So I might've received a new IP adres back then, thats about the only thing I can think of.

 

that is more than likely it, If your modem/Router pulled a new public IP. Then it locked them. Odd that your main account did not get it.

 

My main account dates back to 08 or something, been hacked a couple of times, been banned a couple of times (not for botting, but for calling people twats and stuff) andsoforth. Also logged in on many IP adresses with it, friends, LAN parties etc. maybe they didnt see reason to lock it?
