how do I get a lot of rep on steamtrades?

By making trades with a lot of different traders and it's also helpful to be on both sides honest and open. :3

I'm long retired from trading but I got quit a few rep doing the above. :-)

errr - trading might be the best way - but I don't trade much so cannot be sure :P

Trades ?

Make a lot of trades, get a lot of rep and then deal with impersonators...

asking for rep sounds a little scammy :b

Since rep represent for successful trades, there's really no other way to gain it than by actually trading.

Some easy trades are getting bundle games you want by trading them for cards.
