This is absolutely bonkers to me. We're not here to be scientifically experimented on or to make you feel better about yourself. The very idea that OP learned about places and activities that people participate in explicitly to be social and, instead, chose to touch people when they're not clearly wanting to chat is just wild.
What do we have to do to discourage you from touching us?
I mean I guess I'm glad that you're trying to resolve your anxiety. Self improvement is good for some people. I just wish it weren't at the expense of others.
There was no mentioning of OP touching or taking advantage of others. I think you read this the wrong way.
dpkirchner was right, I did mention tapping people on the shoulder to get their attention. However I thought about it and I could only remember doing it once; the rest of the time, being in front of them was enough. So I just updated the article and removed the "tapping people on the shoulder" part, if you can't find it

"Then, I would approach them, wave or tap them on the shoulder to get their attention, and then give them my opening line."
