Startup IDEA: AI Chat bots promoting goods being a friend

The idea is to a create a network of chatbots acting as real people on various social media platforms.So this network of bots would be chatting/conversing with various people online and will eventually become their virtual friends.

So now for example a company approaches our startup to promote say mobile phones ,we will use this network of bots to create an artificial word of mouth thus giving sales a boast.

This network of bots could also create a community which could be used to create fake FOMO and promote brand. For example a community created contains 90% our bots and 10% real members so with these bots web can create a trend in the community and introduce FOMO in the community to expand sales.

Or you could just, y'know, NOT make the world a worse place for no reason.

Be aware that beyond being spammy garbage behavior, this kind of thing is also literally illegal in some regions since paid advertising needs to be disclosed.
