Thanks for the welcome, but I was kicked off immediately?

How did you find PF?

google

What is the purpose of a welcome message when I was kicked off immediately?

You weren't kicked off (banned). You were given a warning for the spam link you posted in your original Introduction thread, and that thread was deleted. Please do not post spam here in future. Thanks.

It wasn't spam. How did it get classified as such?

And how can I get kicked off?

It wasn't spam. How did it get classified as such?

It was a link-only post with no substantive content, and it was your first post. That is spam. It was classified as such by a member who saw it and reported it. Then a moderator looked at it, agreed with the classification, and issued the warning. FYI, having looked at it, I also agree with the classification and the warning/deletion.

It was classified as "minor" spam because it was at least relevant to the topic of the thread, hence the warning instead of an immediate ban. The assumption is that you are at least not a bot, so you deserve a chance.

And how can I get kicked off?

Per your request, I have banned you. FYI, this request makes the classification as spam seem more correct. It makes it seem that you had no interest in participating beyond promoting your link.
