Not to be flippant but did you ever consider the fact the you and hundreds (thousands) of divers going to this site "numerous times over twenty" are a significant contributor to this problem?
As long as reposnsible practices are followed (I know, a long shot) - fixed moorings, DMs enforcing behavior etc, there should be little impact from dive activities. I've seen both, reefs hammered by overuse and reefs I've done dozens of times that remain healthy. My understanding in the GBR (at least as of the last time I was there about a decade ago) was that they would rotate reefs available for diving to help avoid this
But in Cuba, I can't imagine there's a whole lot of responsible management going on. Although at least until now those reefs aren't seeing GBR type numbers
The biggest risk to reefs, especially in Indo, is irresponsible fishing practices by locals (blasting and/or chemicals)
