banned after long absence of playing

[MsLungen]

Your Warcraft III username: MsLungen
Realm/Gateway: Northrend
Why are you banned: Range Ban
Why you should be unbanned: Hey Ent-Team, I havent been playing Legion TD for maybe one or two years. Now I heard you updated the version and I wanted to try it out so I downloaded wc3 again and wanted to join your ENT Legion td mega server. Unfortunately I seem to be banned but I cant really tell why or how? Does this mean someone has used my Game Key to create an Account?
Thank you!

Hello MsLungen,

Looks like you were caught in a rangeban. To get this sorted out, I'd appreciate it if you would answer the questions below:

Provide a list of all your previous accounts you've used on ENT.

What games do you play on ENT?

When was the last time you played on ENT?

Please answer these questions in full. Thank you in advance.

Hey Until,
the Accounts I used were:
MsLungen
JimPanse
I almost only played Legion TD in different versions, the [mega euro] and the [Mega] were the ones I played mostly. But I maybe tried out some other maps but maybe once or twice only?
I can not tell you exactly the date I played last on ENT but I would suppose its somewhen around September 2016? But this is really just a very vague guess...
Can you tell me what a rangeban means?
Thank you

I can whilelist one account for you to use while playing on ENT Gaming bots.
Please list the username and realm you wish to be whitelisted on.

Do note, you may switch the username/realm once per two months.

@MsLungen

A range ban is a range of IP addresses that have been blacklisted from playing on our bots. This usually occurs when a user is using a VPN/Proxy, or have dodged their ban.

Okay, I don't even know what VPN or Proxy is but it doesn't matter anyway^^

if you could whitelist the username
MsLungen
on Northrend/Europe that would be awesome!
Thanks a lot!

I have whitelisted MsLungen@europe.battle.net
If there are any issues with the username i've whitelisted, please let me know.

Just a reminder, you can switch your whitelisted account once every two months.

Enjoy your games.
