I just checked their Discord server and from what I understand, they are supposed to report their wok in dedicated channel in ordere to get the reward and I haven't noticed anyone sharing bitcointalk screenshots so I think these shills might not be connected with that contest. Either way, whoever Bitget hired to do this is better than those standard shills that usually write inside the project's announcement thread.
The proof should be posted in ⚡│rp-claims channel and yeah I also not found any screenshot about this forum in there, but I only scrolled to the next few days before, it's too much to scroll until the first message lol.
Maybe I'm wrong, but I could be right, after all it's not make sense for these newbies to keep mentioning this scam exchange across to different threads.
