How do I block someone from sending me flirts?

Quick solution

Select the block icon listed next to the flirt you are viewing.

Show me how

1. View your received flirts. Find out how to view flirts if you're not sure how to do this.
2. Select the flirt to which you want to respond. This will cause the flirt message to expand, revealing the response form.
3. Select the block icon. It like a white circle with a diagonal line through and on a brown background.

Remember: the flirts page will only list flirts up to three weeks old. Quite frankly, if you don't respond by then its proably too late anyway.
