Yes, sounds like nasty fraud by lowlife scammer. They put some one tiny notice hidden in their "news". I have never seen anything like this. Any exchange that I have account with gives a prior official message on their site, clearly stating visually in their news which cryptos are going to be delisted and give plenty of time to remove the funds.
They also contact everyone individually with e-mails - this is fundamental way of communicating.
They also repeat the e-mail and news soon before the deadline.

It is 100% premeditated behaviour attempting to sneakingly acquire someone's funds for themselves (aka rob them). I suspect that company is in debt and is trying to fraudulently find ways to get extra source of funds.
