Allow traders to set their Steamgift profiles to show potential imposter warning.

As many already know, impersonating trustworthy traders is one of many ways that a scammer will try to scam people.

They'll change their Steam profile around in an attempt to make themselves look like a trustworthy trader by changing their username, avatar, and such to try to match the trader's profile. They'll then contact victims directly from Steam, and in order to have leverage in a "trade" so that the victim goes first, they then link them to the trustworthy trader's real Steamtrades profile, hoping that the victim doesn't notice that the scammer's profile doesn't match the real user's Steam profile.

Basically, I just found out that I am being impersonated in such a way. Fortunately, though, someone did notice the difference and told me, and I've done what there is to do: report it via Steam, Steamrep, and Steamgifts. But all of those take time, understandably.

I was thinking, though, that because imposters often link to Steamtrade profiles, as mine is most likely doing, I feel that allowing users to activate a sort of warning on their Steamgift profiles, which would be blatantly visible on there, would be something that could help thwart such attempts. Of course, once the scammer figures out that you're on to them, they may simply impersonate someone else, but it makes it inconvenient for them, and although they may move on to someone else, it could still help potential victims until they do. If you're in my situation where it's currently happening and you're aware of it, It would at least allow for some sort of immediate action rather than having to wait for it to hopefully be taken care of.

Originally, the thought was to simply allow users to create a custom message for their profile, but I assume that isn't already a thing due to the fact that anything user-defined means more content that would require potential moderation. If I'm wrong, however, that would also be a welcomed, much more used/useful feature instead.
