Speaking only for myself, my policy is that I don't teach picking techniques unless I've personally known the person for two years.
You can find many forums on the web, but that's out of my control.
When I was new at locksmithing, I was completely fascinated by picking. Now, after 20+ years in the trade, it's an important part of the job, but not totally fascinating. There is so much more to the job.
The reasons I don't teach picking are several.
1) There is no way to know who is the person asking. Most people asking (or lurking and reading the posts) are decent people, but a few are not. So, I've decided simply not to say anything to anyone.
2) Picking locks is a "trade secret" like many other trades which have their techniques and systems.
3) A very small part of the security of locks is that so few people know how to pick them. So, by teaching lock picking, I make all locks less secure for the world. Not what I want to do.
4) Purely selfishly, I learned lock picking the hard way, with lots of practice, and you can do the same.
I wish you well. Hope this doesn't sound unkind, but the world isn't a nice place sometimes.
To reply to your post, a bit more specifically. When you start entertaining people by picking locks, you are sure to get a lot of folks who ask questions. How did you do that? Show me how? What is that tool? What does it do? And as more people learn more about picking, then your car, house, tool box become less secure.
Second question to consider. Do you really want people to know that you're a lock picker? That will make you a high profile suspect every time something is missing, moved, or whatever. "Musta been Locut... he can pick locks".
