For those of you curious as to why less OMM applications are being submitted and why it seems there is a "dry spell" for OMMs, the reason is simple.
Flashback five years ago, market giants weren't as strong/common, gold trading among non-super trusted users happened more frequently, and on top of that the RS market was much MUCH larger.
Current day - Market giants rule the GP market, and that's one of the most common markets for using a middleman, or at least it was.
The most common trades I have middlemanned or seen being middlemanned lately would be account trades of any sort in any game. RuneScape, League, ETC.
Nowadays, not everything is as simple as RSGP for PayPal. There's a massive RSPS market, cs:go market, league market, steam market, etc. Yes getting the proofs are harder, but that's also a good thing because it essentially forces a middleman who wishes to become an OMM to learn the trading styles of other markets in order to complete the proofs. You basically have to learn to MM a variety of trades, or getting your proofs will become much much harder.
Another thing that I think a lot of you are forgetting is that being an OMM isn't 100% about trust, if that was the case then why wouldn't people like Divica or MrEvilPwns just be easily granted OMM with their 1,000 vouches or $500 donor. Part of being an OMM is an underlying "guarantee" that you know what you're doing. If I look back to the first 3 months I was MMing trade to now, I've learned a hell of a lot. You learn how to navigate certain trades, you start to learn when things are sketchy, how to send a proper PM, how a user acts when they ACTUALLY want to trade vs when they want to imposter you.
There's a lot more to being an OMM than a shiny rank that displays "I went through a hard process and have good vouches"
Part of the application is a user showing that they know what they're doing. That's why I would say the application doesn't need to be changed, but I'm open to opinions about the system and additions/subtractions to the project as a whole.
