The problem with this approach is that it's high reward but also high risk. On the one end you have Airbnb spamming Craigslist (which at worst could have resulted in a cease & desist preventing future use of that marketing channel) and on the other end you have Theranos setting up a fake lab and producing fraudulent blood tests. "Be bold" and "fake it till you make it" are good slogans, but there is always a gradient between boldness and reckless negligence. "Take calculated risks" just doesn't have the same ring to it. If OP gets banned by Discord and Slack, their product is dead in the water and they'll have to deal with angry customers who paid for a service OP can no longer provide. This means if this really is a TOS violation, they'll either have to fly under the radar (which arguably failed when they hit HN front page) or they need to grow influential enough to enter negotiation with Slack and Discord to get a special deal.
