Their delisting of tokens is quite shady and I think the bottom line is that if you do have funds on liqui, no matter whether it is actually delisted or not, take it out. There are not a trustworthy exchange at this stage.
I don't see how it's shady. As far as I can see, they have done everything needed to notify users that coins will be delisted. The only debatable aspect is their time frame in which they expect users to withdraw their funds.
There is a saying: you get what you pay for. I think that's the right way to describe these exchanges. If you want better, more professional service, go to an exchange as Kraken or Binance, it's that simple.
People have to accept that these things can happen when they bet on shitcoins. There are over 10,000 coins and tokens in existence, try to pick one that doesn't screw you over one way or another, it's simply impossible.
