all these are because of Sinbad which was used by Lazaro. but it's not Sinbad's fault they were picked by the Lazaro group and Lazaro should be their target, not the mixers.
if authorities are up to finding them, they should just follow the trails. killing mixers business will just make their job harder as it will be done in a very secretive group. it is harder for them once mixers do the most innovative ways like using AIs and telegram bots.
In a situation like this, it's only the innocent users that will be affected negatively because the criminals will find their way around it and find a way to mix the stolen coins within available means to continue with their criminal act.
Although not only Sinbad but also other mixers that were seized back then early this year who had their promotion here in the forum since 2017 be for it was seized by the same FBI chipmixer and this made the incident the second which caught the attention of the admin.
