How to be a concern troll for scamming purposes:

1. Say someone did something that contravenes some virtue your audience cares about

2. When that person defends themselves and calls you out or adds nuance, refer to them as toxic

3. Make the issue about toxicity with your new examples of that person calling you out

4. Emphasize that your product / coin etc. is not toxic like that person's product / coin

5. Profit
