The worst that could happen (if it hasn't happened yet), is for the authorities to request information about the user who allegedly represented
ChipMixer here on the forum.
I referenced this on previous page that authorities didn't publish that they requested information from bitcointalk, despite making a lot of references. At least, they didn't publish any evidence from any requests that is.
a particularly strange part of the
court documents highlights how far the reach of warrants to different services extended (or records provided) by the likes of; Google, Yahoo, Protonmail, Paypal, Binance, Dropbox, Apple, LinkedIn,, Twitter, Reddit, Hetzner, DigitalOcean... basically
everyone and anything to do with the inveestigation, but bitcointalk wasn't referenced as included?
So they might well of done so (and probably did imo), but if the IPs were from VPN or otherwise obscured (which is very likely) then they didn't publish the results as part of investigation...
