Talking with individual players and take them to the scam site is a time consuming job. Pasting the link of the scam site here is unfortunately an easy way to market the scam site. Some people don't even read the reviews and just click on the link to play.
If you doing it by yourself - yes, this is really hard work with a little profit. My words were not entirely correct. I meant using the bot to invite or add you to some channel, where is the scammer and several his other accounts that telling you how this casino is wonderful. In this way - this is easy way to make newbies to deposit their money.
