One of the fundamental properties of junk mail is to ensure that it is sufficiently riddled with poor spelling and grammar, thus making only the very stupid fall for the underlying scam.

Dash kinda functions in a similar manner. If you look at the Dash userbase - that is to say those Dash users that have not deserted - it is only really the very stupid that remain.

Thus, it functions as a kind of of Hornet's Nest operation - a "Dash trap" ensuring that only the very stupid users are waving the flag, bringing new stupid users in, and consequently allowing for an environment where the userbase are prisoners of their own stupidity. The effect of their stupidity ensures that they are unable to discern the qualifications of a good/bad project, thus keeping them all trapped together in perpetuity.

The plus side is though that it effectively quarantines all the unintelligent users together and keeps them from escaping into better projects where they might allow their dysfunctional idiocy to spread.
