Ultimate RMT Spam Killer.. Us.

That's why you limit it to one report against any given player per SE account.

If you read again what I stated, I already addressed your 'create another bot' concern with the 5th sentence.

If any given player receives more than 5 'Report as RMT' flags in 30 minutes, block the account (not just the character) from being able to send TELLs or Friend Requests for, say, 1 hour for the first offence. The 2nd offence could be 12 hours pending Task Force review.

SE will not ban entire ISPs, and you'll never stop people from buying gil, just not the way the world works.. So while that eutopic thought is nice, it's never going to come to pass.

If you're that concerned with bullying, then simply increase the number of reports required to 10. The odds of you getting 9 friends to deliberately harm another player in such a manner, I think, are small.. There's also GMs to assist in such manners as making false claims (as it's considered harassment) could be a punishable offence, which should deter most, if not all, potential offenders.

Edit:
Lastly, your bullying is still possible with just a couple more mouseclicks, you can report anyone ingame for harassment and/or cheating, which gets them put up for investigation anyway. So my idea wouldn't really add any increased risk of harassment.
