I'm going to start by saying, well...most of you are fucking stupid if you think the RSGP black market/botting provides Jagex with more revenue than legit players.
Uncalled for.
By viewing the main Runescape page, and going through their links/pages you're viewing their advertisements which generates A LOT more cash flow than the membership from bots. By using a bot client, you're skipping them then logging your accounts in, which - in turn makes them lose A LOT of money.
It's true Jagex does earn a lot of money from the advertisements on their site, however that is no proof they earn more money from legit players. A big part of the legit Runescape community uses clients too, which would mean the same thing. Besides, the majority of Runescape players are botting. Proof is that there are much less players playing after an update, when the bots don't work. Fact is, there is a very large amount of bots with membership, and they do earn Jagex a large sum of money every month.
All this bullshit about 'oh, there's more bots than actual players so they won't ban us because of the money they make from us' is complete, and utter arrogant bullshit.
I agree that 'they won't ban us because of the money they make from us' is not accepted by Jagex and they do ban macroers. However, Jagex doesn't appear to care much about the macroers. Sure, they ban a small part of the bots, but they don't add much new systems to prevent the use of bots. They don't do as much against them as they could do.
Membership for 1 Character per month is on average £3-5
A LOT of these are stolen, and Jagex DO NOT profit from these, in which if a goldfarmer were to be running a goldfarm they would obtain these ILLEGALLY and as goldfarmers and goldfarms make up the majority of these 'mass accounts' that's a lot of money being lost, added to that they aren't viewing the Jagex Website so Jagex aren't making money from them that way either. 1-5 with legitimate membership DOES NOT make up for losses.
I highly doubt 'a lot' of memberships are bought with stolen credit cards. Almost none of the accounts upgraded with upgrades sold on this site and other blackmarkets are given a negative credit balance because they were bought with stolen cards. Or, at least, that's my experience. I don't see any proof to support your point.

They generate those amounts monthly, permanently, and get extra via traffic. Thus, they make more money that way.
Jagex makes much, much more from advertisements and membership. Not sure why you post a site which is not registered to Jagex. Again, this isn't proof to support your point.
I do understand where you are coming from, but you post a lot of unproven stuff in a very rude way. And, in my opinion, most of what you said are pure assumptions which are very unlikely to be true.
