Well most of them are Alt accounts, so they not going to be bothered if they are going to get banned for a few days or not for rain farming. In any way... feeding a Alt account to reach the $3000 wager requirement is not going to be worth it... just to rain farm. (It will cost you more than you will gain, if you had to wager $3000 to qualify.... and during "reloads" the chat is full of people that are just there to milk the reloads and to get some rain.)

The mods know this.... so they are super vigilant and I have already seen several people getting banned for rain farming these last two days.
