It is difficult to write about something illegal. That’s because the sources are hard to check and those sources try to talk in the vaguest manner, hiding the most important facts. Thanks God for the Internet where people speak openly about illegal stuff – like it is talked about some toy store.

We may start with "Observer" article, which says about a woman who played in New York underground clubs in the second half of 2000s.

“The game took place in nondescript buildings. Instead of nice dresses I wore sweatshirt with a hood and headphones. There were cameras everywhere, sometimes I had to get through burly securities. Some facilities issued IDs. However, security systems were always dull and ineffective. Cops could enter the room almost as easily as robbers”, remembers the hero of the article.
