The last update is from December, and since that time, a new mixer has joined the exit-scam list, and some mixers may change the seriousness in their dealings with customers, especially since promotion will become more difficult due to the disappearance of bitcointalk signatures.
If altcoinstalks succeeds in attracting these services, then there will be good discussion about them here and the table may be updated regularly, reducing the possibility of you being scammed.
