I've been here for about a year ( I've lost my other account) and I noticed people here get to have a + reputation whenever they participate and complete a trade or any lending or payment transactions.
Now I am wondering if there is any other way to build a reputation here besides participating any transactions?
Actually, it is not +reputation. It is +
trust.
You cannot gain/build trust per definition. Trust is earned over a long period of time showing that you can be trusted.
It is a little like the chicken and the egg paradox, nobody will trust you if you have 0 trust.
But eventually people will trust you based on your post history and generel behavious.
If you are just a spammer or try to buy trust, then will you actually do more harm than good.
You can earn your trust if you had many dialogs with other trusted members and they reconize that you have a mind set that is unlikely to be a scammer.
