The case you cite, "the SR server was located by myself and another member..." is not ambiguous at all. For "by myself" to take on the "on my own" meaning, the sentence would need "I" as its subject:

"I located the SR server by myself.", not "The SR server was located by myself", which I don't think anyone, even those using this objectionable form, would produce.

I understand and sympathize with your distaste for the expression: it goes against previous rules of formal written English, and it signals the style adopted by people speaking for organizations attempting to convey power and control, which goes against the anti-authoritarian ethos of HN. But these sorts of judgments are usually motivated by deeply-held feelings and then rationalized as pleas for clarity and precision in language.
