Yeah, 1000% I was put off by their behaviour, more than anything else in the thread. The URL not matching was absolutely questionable, and if OP had said "whoops, typo" or even just "huh, weird" I might've accepted it, but instead they acted like they got caught splicing a speedrun world record, high and mighty and like it was offensive that people wouldn't just click any link a stranger sent them. They were rude in nearly every comment on the whole post.
The whole thing put me off, and that's when I downvoted the whole thing as a potential phishing scam and silently left the thread.
