If you look at the list of stocks you can all see they are super super tiny companies so likely it is fraud schemes aka pump and dump. That's when a small group of people (typically) organize an effort to pump a stock using false information. Since these stocks are so small, even getting a few amount of small investors to buy in could result in significant profits for the fraudsters. Doing a pump and dump on a stock like GME would be extremely difficult to pull off.
