It is clear at this point that while I don't think my original comment (or similar previous comments) was asking for advice, plenty of other people do indeed interpret them as such. If this were simply a choice of words that had a common meaning I was unfamiliar with, I'd happily accept this and move on, but in this case I think these other people are fundamentally doing something incorrectly with language and dialogue.

My immediate case for this is threefold:

1) The comment is literally not asking for advice. It does not execute the speech act of asking for advice.

2) If someone were to infer a request for advice from the comment, they would notice the comment does not contain sufficient information for them to provide good advice. Even if it has the superficial appearance of implicitly asking for advice, it is not well-suited to this task.

3) If someone were to go about the process of asking me for the salient background information to offer me good advice (rather than just shooting in the dark and generating irrelevant discussion that doesn't serve anyone's purposes), they would notice that it wasn't a request for advice. This casts doubt on their motives for engagement with the dialogue, not to mention their ability to give appropriate advice.

It's not a request for advice. It's just not, and it's pragmatically unsound (not to mention kind of rude and really annoying) to interpret it as such.

So yes, I think I'm right, and everyone else is wrong. I should point out that although I find the unsolicited advice incredibly annoying, I find the underlying discourse phenomenon really interesting.
