2024/2025 NFL Survivor Contests

I'm planning to play the Circa Survivor for the first time this coming season and have already booked my travel and arranged my proxy service to make my picks for me. Last year I made it to weeks 14, 15, and 16 in DraftKings various survivor pools (the $100, $10, and $1 entries). Does anyone know or have experience regarding how players communicate with one another to discuss chops/deals as it gets down near the end? Is player contact info public?

On another note, is it pretty much a given that a chop is realistic nearly every year sometime between weeks 14 and 16? I've tracked the results going back to 2020 and that's what it looks like. If you are banking on a chop without having to play weeks 17 and 18, it probably makes sense to not leave any top tier teams for the final 2 weeks, as there's a better than average chance the prize pool, or most of it, will be chopped.

Thanks all!
