From what I saw, not at all - it was seen as useful by most people I knew of all different trades ... but later on when searches improved, there were some realisations that some people had shared way too much of their real life details. As such I recall there was an educational effort to prompt people to avoid sharing details that might be used against them. I can't say for sure but I think over the next couple of years a few things were changed within what search engines could search for (eg bank branch numbers became harder to confirm) and eventually especially after iirc M$ complained, removing any real public string search capabilities.
