Steamrep is important, but sites like Steamtrades have a decent rep system since only 1 comment can be left per Steam account.

It's unlikely that a scammer will have 50 alt Steam accounts just to boost rep, so if you see someone with +50/-0 it's a pretty fair bet that they are OK.

As I mentioned, I have done over 70 trades on steamrep all all have been fine following the "higher rep user goes first with keys" rule.

There have been a number of features that haven't made it into the final client, I know this for sure because of users in some of the chats I frequent commenting on new things in their client which I didn't see when they mentioned them, (as I haven't opted in to the beta) and never had seen implemented since. Although, I can't think of any right now, as I have no interest in opting in to the beta, so quickly forget when such a topic of conversation comes, and goes.

As to why it's a flawed and ridiculous solution? I already commented on that in a different comment, let me copypasta it:

"1) It was a feature which could be used to much comic effect, and a useful extra option that increased ways to express yourself 2) UI and its' features should never be crippled due to user stupidity and error, if the referenced feature isn't somehow inherently flawed,- which it wasn't."

Also, DoctorRagnarok made a comment on this also which sums up quite nicely this quite core idea in IT and software development / management:

No matter how much security a company provides its customers, security means nothing if the customer does not do their part in keeping themselves safe. As much as the intention behind this may be good, it's not likely to make any real change in the end. We don't need smarter technology, we need smarter people.

You don't cripple UI because users are too dumb to realise they're, for example, being scammed. Why? For a number of reasons.

1. Thinking along such lines, you'd have to keep reducing user functionality and input to a ridiculous degree, so much so that you'd end up with a crippled client. Where does limiting user functionality end? Disabling the trade window? Disabling the ability to input keys? And no, this isn't exaggerating the issue - removing those features would actually make more sense if you're thinking about limiting scams, as those 2 actually give scammers a way to do what they do in a practical sense - /me doesn't do anything other than give them 1 way to fool ignorant people.
2. Because you give users a false sense of complacency and trust in the client by having simply cut off one avenue scammers took. People that lack the wariness and presence of mind needed to protect themselves from such crap online to begin with will simply hear of this and think "ah, steam's safer" or even "ok, now steam's safe and I can trust what goes on there" - which it still isn't; removing the /me command hasn't actually made it safer in any way whatsoever - but you have made users more complacent and trusting, which can even have more negative repercussions in the long run.

The amount of scammers hasn't gone down, the amount of ingenuity they try to exhibit to scam people hasn't, and neither has the level of ignorance of the people being scammed - which is the only factor that would decrease the amount of users being scammed, if it were tackled somehow.

This removing of "/me" will probably decrease the amount of people being scammed by a very small percentage, for maybe 2 weeks or so, tops, (and that's giving it a lot of time) before scammers find another angle with which to work the same people, with the same amount of ignorance as to online scams.

As for "I'd like to see just one situation where that could be useful. I've never ever seen anyone use it outside a scam attempt"? Then you musn't hang out in very many group chats. I can provide whole chat logs where /me was used to quite comic effect, where whole stories and scenes were set using the command. Anyway, it's quite irrelevant whether or not it was never used, used every day by every user, or even used purely by scammers - as I explained quite well above.

Ah, reading through comments here, I see more funny comments that illustrate part of my argument:

Someone used the internet to try and scam me, we should get rid of that..oh and the telephone and postal service.

Smashing my mobile phone later, had a PPI scammer text me.

Scammers, con-artists, thieves, will always be a part of any system or new technology released to the public. People need to learn to be wary and more careful, period.
