One of the first mods on sale in Valve's recently introduced paid mods program has been taken down.

Valve recently introduced paid mods to its Steam Workshop, starting first with The Elder Scrolls V: Skyrim for its already sprawling community.

The content in question was a fishing mod that used assets from a second mod by separate creators.

It isn't uncommon for modders to require another creator's content for their own to function, but with money in the mix, things get a tad complicated.

After accusations of stealing and unfair profits were exchanged via the Steam Workshop forums, as saved by Destructoid, the fishing mod creator took the content down and issued refunds.

According to the modder, Valve gave specific permission to sell the mod even though it used another creator's free content: "I was told that if the download is separate and free, it was fair game."

We've reached out to Valve for clarification on paid mod guidelines and will update with any new info.

For now, we know that several Steam users and modders are upset with the introduction of paid content on Steam Workshop.

An active petition on Change.org currently has over 126,000 signatures asking Valve to remove the program from Steam.
