Yes, the user has some suspicious post history and I have some solid proof that the accounts has changed hands between 2015-2018 as we can check by its posts history.
@Pharmacist
I found a very interesting proof that the account has changed hands and is not in the hands of a German person anymore as,
This is a Post on
IPL( Indian Premier League) Prediction Thread, 2018. I think KKR had the better chance for fourth spot because they also have well balanced team but they are not playing well in the last match,I hope in today's match will be more interesting.But we can't really predict the tournament at these condition because anything can happen still MI also have chances if they win six matches in their total of seven matches so it is getting more interesting while the tournament get progressing.
Indian Premier League is an Indian cricket sports event and it only takes place in India so I don't think a German person ( German players also don't play cricket in the event ) would know this info and predict a match in any way. So, we can say the new owner should be of the Indian Nationality. Also this account has no previous interest in any sports until 2015.
BUT, even though it seams a change in hands of the account, the new owner is in no way spamming anything on the forum and also handling the account in a spam-free way from much time now. So, I would suggest not tagging the account red for this or just put a neutral about change of hands of the account.
