So I guess thanks YoMix for putting me on an FBI watchlist. Be warned anyone. If it's so easy for an exchange to detect a bitcoin "mixer" it sure as hell means that it's not an actual mixer.
When you are using mixers you need to be creative. I think it's depend on individual experience level. Personally I will not give up my strategy and want someone else to adopt it to make it became common. I use mixers a lot even in the recent time I used one of the mixer [not calling the name for obvious reason] that is advertising on the forum. Thankfully I never had any such experience.
Besides when there are no information given to show the validity of the reason they gave, it's hard to make a conclusion too.
