Ah, I see you misunderstand the fallacy. The bandwagon fallacy, holds that it is fallacious to say "most people think x, so x is certainly true true" (deductive reasoning), but not that it is fallacious to say "most people think x, so x is probably true" (inductive reasoning). In fact, the "most people" approach is generally quite accurate - see for example the success of the "ask the audience" lifeline in Who Wants to be a Millionaire - estimates at 95% success rate

This case involves the interpretation of what someone (lux) was saying, so obviously it would not be possible to reach a certain conclusion, and I did not suggest that the preponderance of opinion suggested a certain conclusion. However, if near everyone understood a set of questions and comments to mean a certain thing, then it is perfectly valid to say that is probably what was meant.
