PLEASE change level requirement to whisper ....

To be fair those are their "farmers" they won't risk sending tells with those because they actually take time for them to replace, Unlike level 1 bots that are just erased/banned and replaced quickly after. it would certainly hurt them and i fully agree with this.

They wouldn't send advertising spam with their farming bots because those bots are accumulating the gil for them to sell. They don't want that gil lost when their spam bots are banned, so the two types are handled through separate accounts. I don't think Nadirah was suggesting they'd actually use the same bots, just that having farming bots proves they're quite capable of automating bots that will level up.

Currently RMT spam-bots are left at level 1 only because they have no particular reason for making them higher level, but if they did have a reason (like for instance the OP's suggestion being implemented) then the RMT companies would simply level all their spam-bots up to whatever level they need them to be. We'd still have just as much spam coming from just as many bots, the only difference being that those bots would be level 10 or 15 or whatever instead of level 1.

Then won't RMT just go back to spamming friend requests?

Friend requests aren't as effective as actual messages, since the only actual content passed with it is their character's name. They used that when it was possible to do so with free trial accounts, but it stopped when the Free Trial restrictions were updated to block friend requests. Now the only place Free Trial accounts can spam is the /say channel. Everything else needs a paid account, which they focus on their most effective spam method: /tell.
