Let's look at the profiles of the 2 accounts that used this totally normal word:

1. @shantnutiwari, with an account that is over 1-year-old, who has 2 websites that he seems to still maintain.

2. @chrisrickard, who directly linked his Twitter account, and to me seems like a pretty real human being.

Would be a lot of effort creating all of this for some engagement on a post don't you think?

If you don't like the guide it's completely fine; I don't expect everyone to like it, but don't make false accusations.
