Saw this on Xiaohongshu—could it be a forum buddy? 😝

Just click into their profile and check the bio or IP location, and you'll basically be able to confirm it.

On Xiaohongshu, do you search by keywords or just scroll through the recommendation feed? If you search, the specific terms you use might make it easier for forum folks to recognize you.

If you claim someone as a contact just because their profile picture or username looks similar, you might sometimes get the wrong person—especially when they've only reposted content or happen to share the same name. And if you DM them directly to ask who they are, more particular users might take offense. It's safer to first check whether they've proactively left a signal in their posts.

So is this definitely a forum member, or does it just look like their content?

You can first check whether the other person's profile has links to other platforms or a fixed code phrase, and only interact once you've confirmed there's some overlap. But if they clearly don't want to reveal their identity, don't keep pressing.
