GameStop stock has been removed from the Robinhood trading app, with users claiming the site had blocked sales of the video game retailer’s shares.

GameStop’s share price reached as high as $380 on Wednesday, up from $18 a few weeks ago after those on the subreddit r/WallStreetBets invested in the company. The stock value has risen a total of around 1,700 percent this month.

“THEY DONE TOOK $GME AND $AMC OFF ROBINHOOD,” wrote one. “They were like “no, the poor shall will not know our ways.”

Another said: “You can no longer buy GameStop stock on Robinhood. Ditto Nokia, AMC, and all the other stocks that had been shorted.
