Which things you can farm and sell for plats in game?

[Nailclipper]

Let's list them here:

• "Trash" prime parts
• Corrupted mods
• Requiem mods (Jahu, Vome, etc.)
• Unvaulted relics (a handful of people do buy them in large quantity, don't ask me why)
• Bounty mods: Augur Secrets, Gladiator Vice, Tek Enhance, Tek Gravity, Argon Scope, Weeping Wounds, etc.

If you know more, please add them. I consider rivens to be not farmable.

For those who said syndicate items, I think it's only true if you are aligned with any faction except Steel Meridian or Red Veil. Even then, you can't really farm them because your max standing per day is capped.

Obtaining items that you can sell for plat doesn't mean, you actually sell them in the same speed you "farm" them. Problem with plat trade is, it depends on the market / request. 
Therefore, I consider every way of stock up some tradable items as a way of "plat farming" over time. Depending on you play style, you caneven think of long term investment wifh farminge cheap prime parts, waiting for times when they are vaulted.

There is simply no way of [action]-->[platinum].
