How does your perspective differ from the perspectives that led to the imposition of the Residential Schools?

Also, nothing I wrote says anything about providing them with access, it says something about destroying their culture and identity. So don't be too quick to make assumptions about what I believe or don't believe about medicine and education.

Help is exactly what I would want from advanced alien visitors. I don't want them to respect my culture just because it is mine; I want something better for myself, not cultural relativism.

There is nothing good or enviable about uncivilized lifestyles to preserve; any actions that maintain them in that lifestyle are ensuring they literally die young, mostly of preventable causes. Their lives are short, uncomfortable and brutal. Trying to minimize contact is ensuring they do not get modern medical care and that they retain their dark ages quality (or worse) myths and prejudices.

Celsius, Fahrenheit, what's the difference?

Point being be careful with your error messages they might give away your users anonymity.

There is no valid reason for storing plain text passwords. Every time someone says "but we want it because we need to X" there is a better way to achieve X (or Y, where Y has the same effect as X in the end) that does not require plain text password storage (but may require a little extra coding+testing).

If anyone who says that the "but may require a little extra coding+testing" constitutes a valid reason, then they should not be trusted with any of your data. It is like leaving the office door unlocked because you couldn't be bothered to fish your keys out of your pocket and find the right key. It is an excuse (a pathetic excuse) for plain text passwords, but it is not a valid/good/acceptable reason.

Of course there are probably a great many sites that are unprofessionally constructed (in the auth credentials storage area at least) and you may never know until something goes wrong, so for safety you should not use the same password for multiple sites (keepass and similar utilities make keeping track of multiple password easy enough) then at least if one site is hacked the perp only gets access to that one site as you rather than potentially many sites.
