From your post history it looks to be clearly signature post spam. Not spammy spam, but posts clearly made to increase earnings from a signature campaign.

Getting negative trust for doing it is pretty stupid and whoever Laura is they need to rethink their situation. A more suitable warning for others would be a neutral letting future campaign managers know that the user in question wouldn't be good for their campaign.

I personally don't see your negative trust on the forum itself as I have removed Default Trust from my trust list as the majority of them are full of shit.
