I dont know who would read it. It was a suggestion made by itch itself. Anyway thanks for your answer.

Well. If you were to have a social media channel, or someone promoting your not yet published project, the post could be linked. But I guess from within the Itch system, there will be zero to none people seeing or clicking the post. I consider it a tool for people that have a following, not a tool to gain one. Follwers will get notified about such postings.
One would have to go fishing in https://itch.io/feed?filter=posts at the right time or scroll there a lot. There is not even a filter to only see blog posts. Most of the entries there are updates.
I learned about these postings, because I stumbled on one of the scam postings by googling a game. So if your project happens to be of interest to people, they might find it by regular internet search.
