That is a silly argument (posting only winners) and a scampish pr move on TST's behalf. Sure we hear about Jim's great Monday when he made 2K, but we never hear about his Tuesday when he lost 3K.
Without a longer time frame (Jim made 10K in January, for example or even better he made 30K in 3 months) those posts are only good for drumming up business.
What are you looking for? You want them to show you 100s of traders making 20k a week? Not going to happen as most traders fail with or without topstep. The whole most people dont take a decent cheque with TST so therefore its a scam argument is very dumb. Most people never earn from trading ever at all. Its like pro sports, most people never reach the required level.

The others just add noise which would make any aggregate statistics useless.
