This is what I took from one of those old Theros articles which leads me to believe they lean more towards evil that good (not that I use alignment but they don't sound like a "good" race).
Also, my comment about the colours was wrong, they are typically green/red and green/black. I had thought that they had red as a common colour.
Cult of Horns
Frequently humans come to Skola in search of endless pleasure without consequences. When they first arrive, they are courted by the satyrs. They are told they will learn the mysteries of Nyx. They enjoy days of revelries, music, and ecstatic dance—all without a care in the world. Inevitably, the hospitality gives way to something more sinister, and these unsuspecting humans find themselves conscripted into service of the satyrs.
The satyr sybils decide when these newcomers are ready for full initiation rites. Many humans undertake the rites, never knowing the joke is on them, and are awarded a crown made of broken horns—a symbol of mockery. Once given the crown, they are known as Stubs. They are assigned menial, humiliating tasks. Enchantment magic keeps them in the thrall of the satyrs until, inevitably, the satyrs tire. Then the Stubs are deserted in the wild chaparral, where they awake hours later, alone, dazed, and ashamed. Out of embarrassment, Stubs seldom tell the true story of their time with the satyrs.
Many perpetuate the myth of the joy and excitement of their time in Skola, encouraging the younger generation to "sow their wild oats" among the satyrs.
