Yeah but even with those services people were not using them because they thought it was anonymous. Silkroad users were one big chunk of those people who hid behind a false notion of it even though it says on bitcoin.org that its not anonymous. There is a lot of misinformation out there on these "walkthrough" and what is websites that are just plain wrong.
Here is a good example.
"The Bitcoin is a system which allows you to do anonymous currency transactions and no one will come to know about the payment or about all other info related to the payment, including who sent it, who received it, etc."

Its really no more anonymous then cash once it enters the black market, in fact it might be less.
