I asked this question 6 years ago and It finally got some good information then the answer was deleted and the post locked by a mod. There was no reason given in comments. I can see closing it but the locking seems overkill.
The question is now off-topic, per the Help Center. The locking makes it much more clear that the question and others like it no longer fit the rules of the site. However, there was good and valuable content and locking preserves that. The alternative is deletion.
