It's been a few years since I bothered torrenting much, but if you don't change the defaults on your torrent client, even then you'd get flagged pretty quickly. Biggest thing used to be not throttling upload speed; almost all consumers are going to be downloading wildly more than they upload, and even heavy users of upload bandwidth are going to primarily be shooting it to well-known destinations. If you start uploading at 100MB/s to random IPs, that looks suspicious.
