Does not in any shape, way or form change the initial 'revelation'. If you can take the first links as IC proof of connection between Jade and that other character (which I'm convinced you can, as it's IC available on an IC forum, and supported by PF stating that the structure of Galnet is very similar to our current day internet), you can easily take the changed links and say "Ah, lookie here, damage control." Once the cat's out of the bag, it's not so easily stuffed back.
In short... changing the links viewed from an IC perspective is just that the characters are doing exactly that, In Character.
It's quite simply a difference in opinion, apparently. My opinion is that it's IC available information, used in an IC fashion to create IC connections between two characters. Supported quite a bit by the use of Rosalyn as an Amarr bashing Jade sycophant, having Revan cozy up to her just like she does with Jade (IC perspective). This has been remarked on, on the IGS, long before the picture links were discovered.
Now, I doubt there'll be any kind of agreement on this point, but here's a recommendation/advise nonetheless:
If you do have multiple IGS posting characters (I personally use just one, to avoid this kind of thing), use neutral/randomized image hosting services. Tinypic is one I am very fond of, as it's impossible to connect between characters. It avoids the entire problem, and allows you to keep denouncing IGS mouthpieces IC while avoiding the IC 'Ahah! But you do it yourself!' thing.
And while I'm stepping closer to the 'urdoinitrong' territory, I would like to make a final recommendation:
Turn Rosalyn Shaw slightly less... well, SF/Jade asskisser. I'm sorry, but that's the impression I get both IC and OoC. It makes her look like she was constructed purely for that kind of thing, supporting SF/Jade posting and denouncing Amarr/SF-detractor posting without having SF connections. That's the appearance I get from that character, and what I got long before these links were provided.
Make her more into a character of her own on IGS. Doing lowbrow humor isn't something that'll separate the character much from Jade, to be quite honest. Anyway, that's just a recommendation, and I'm not saying 'urdoinitrong'. It's just friendly advice in order to avoid these kinds of things in the future.
