I forgot to point this out, but it doesn't help that you have a [MIDDLEMAN] tag on your name. I have crabbed over 50 crabs with pots worth 2 buds and higher (side note, never crab, it isn't worth it), and I have never met a trusted mm with a tag like this. Along with the other factors (your low play time in certain games, your very low level of reputation, the size of your inventory, your low steam level, etc.) make it seem like you're just like one of the many people out there who want to "mm" for someone, only to take both parties items and run. Don't be offended by this. This is the internet, and being that you need be trusted to be a successful mm, people need to judge how trustworthy you are based on certain factors, like the ones listed above. We don't know you personally, therefore we need to be convinced that you are a good choice to trust with our virtual possessions if need be.
To be a trusted mm, you need many hours in games like tf2 and cs:go to show you have a lot of time invested in these games, which makes it less likely for you to ruin your trust by running after mm-ing. You need a high steam level and a decent amount of items in your inventory to show that you are invested in gaming, mostly for the same reason why it is essential to have many hours in tf2 and cs:go. Reputation threads on certain trading websites are also essential, to show that you have been deemed trustworthy by the trading community. Lose the mm tag, it makes it seem like you're begging to mm for others, which is sketchy.
edit: please note there are many trusted mm already out there, and established in the tf2 and cs:go trading community. My recommendation to you is just trade, and get more hours and reputation in cs:go and tf2. Although it is nice to have trusted people in an online gaming community, atm it doesn't seem like more mm are needed.
