How would you identify someone that is using you?

Anonymous
There is someone I know and we talked from to time when he joined the friend group online (some people there I know irl). I can't help but feel that this person isn't being as genuine as they seem to be. Selectively who to talk to and when they talk. Looking at past dms, the things said seemed pretty shallow small talk, mostly initiated by them. Felt like they were just trying to get on my good side and when they saw that's all they could get out of me, they slowly ceased to message me or talk to me, only occasionally. They still heavily message one of my close friends though. Things that weren't personal that could've been easily said in a public chat with everyone else was sent to me as a dm. They've been acting more shady and after seeing those dms again, I've been getting more bad vibes from them. Someone that used to interact more publicly going to selectively talking to specific people (most likely dms) makes it feel like they're just using people to build their image. Even the friend that they brought in seems to act more of a wingman rather than someone you'd bring to be like, "Hey I want you to meet these cool people." as every they interact, it has that "thanks for letting me borrow your lambo" vibe.
