The founder of WallStreetBets, a Reddit forum known for popularising "meme stocks", has sued Reddit in the US for banning him from moderating the online community. Jaime Rogozinski said he was banned a month after he applied to trademark 'WallStreetBets' in March 2020. Reddit called the lawsuit "frivolous" and said, "Jaime was removed as a moderator...for attempting to enrich himself."
