I have open several topics already and warned about this. But I would like to take this discussion a little further now
We don't need so many boards. It is bad for navigation. Topics get lost. People can't find what they want, and it is humanly impossible to track all that we want too.
The idea behind duplicating board with same content is to try to trick search engines to improve SEO. The idea is simple: Just create duplicated content all over the forum, more keywords, more google searches. Right? No!
Google is way smarter than that, and it penalizes websites that does that. This is called
Keyword CannibalizationSo, what is that?
What is keyword cannibalization?
Keyword cannibalization is an SEO issue that happens when multiple pages on a website target the same or similar keywords. This leads to a situation where the site’s pages compete against each other for search engine rankings. This can dilute the website’s ability to rank effectively for targeted keywords.
For example, let’s say we have two pages about technical SEO. If we could get more organic traffic overall by combining the two pages into one, that’s a cannibalization issue. The existence of those two pages is eating away at our organic performance.

This is bad for SEO, and there are ways to fix and identify it.
Look at the image below. Don't we see that all over the forum, on all those duplicated board with the same content?

What is the difference between "Forum Related" and "Forum basic questions?"
Or what is the difference between "Crypto Raffle" and "Random Crypto Giveaway"? There are dozens of examples.
Look at the main page of the forum. I just made a simple Ctrl + F to find the word
forum. Mentioned 85 times. Now write "forum" in google, and see if it redirects it here...

The word
crypto is even more. 96 times! Just in main page
