I have logged in and was asked to change passwords... but, no - I wasn't very active with it.

However, if they took it because of inactivity - why did they give me a replacement username?

My twitter user name australia was changed by twitter to Australia1_

My original user name has been given to Toursim Australia.

I never saw any correspondence about this from Twitter (I may have deleted it), nor from Tourism Australia.

I have managed to send 2 related support requests to twitter;

Once explaining I couldn't log in - and their reply was;

"The email address you're writing from does not match the email on this account. For privacy reasons, we can't offer any more information about the email."

Second time that my account was suspended - they replied;

"If you're writing in about Australia1_ being suspended, this account is not currently suspended"

I don't believe this can be a trademark issue because you cannot trademark a place name.

I would love an explanation from twitter-

Any tips?
