That's well and all... And it's true i haven't seen scam reports about this service so far, and that's a good sign... However, a long time ago i got payed by jambler to review their service, here's my report: https://bitcointalk.org/index.php?topic=5140688.msg51237562#msg51237562

The thing is, it seems like the jambler site admin didn't follow any advice i've given them... The site still uses cloudflare's MITM SSL, security headers are still missing, google analytics are still used, cookies are still missing flags,...
Even worse, it seems components like jQuery have not been kept up to date, and are now lagging behind, exposing potential vulnerability's...

I have no quarrel with the site admin, it seems he's trying to run an honest business (so far), and i've analysed one of their outputs and it seems (at that time at least) he was telling the truth about their mixing algo... However, the security of the actual site is not up to par, so i'd never consider to actually use this site untill these issues are fixed. At this moment, using jambler defeats the purpose of using a mixer... Why use a mixer if cloudflare and google are able to track every action you perform on their clearnet site?
