not at all, my friend. Website promotion is not spam, you are confusing backlinking with advertising
I really don't want to take it that far (into a debate or something similar),
so, I'll just throw my point of view
but google doesn't really get the difference between a website promotion or a normal backlink (built or not),
in the example above, such a website will get natural links that looks the same as guest posts or pbns (without including the traffic),
these links will come from crypto bloggers who want to write about the new coin, news websites and maybe hundred if not thousands of them in a little time frame
your point that google crawler will get these as website promotion rather than links built,
and as I said above, with maintaining the high quality of links, google crawlers will have no chance to actually spot the difference,
if they could spot the differences and already doing, most of the people websites here shouldn't be ranking and none of the links sold or built should be working at all, even if you build 10 links per month
