How do you know they are different people? It's really easy to change your IP adress, everyone can do it. It is too obvious for me that this is 1 person (2 at most) obsessed with Monegal.
We agree that they are trolls. Everybody talks sh1t but nobody uploads x-rays or any kind of proof, lol.
As I said, I'm not sure, but I have some extra data you don't have right now.
First of all, I have a background in Forensic Linguistics. The writing style of these trolls isn't the same. It's obvious there are 2 trolls at least, apart from independent trolls, like Bander72 (who decided to impersonate Dr Monegal for fun in september 2017). I'm not saying that amigos, iwontallow and morpheus are independent trolls. I don't have enough information to reach a conclusion about them yet. Anyway, independent trolls exist. Not all of them are LLuser or Mr Sarcastic... or Forced Puberty. Mods could find about this in the past through IP investigation, because trolls didn't bother to change their IP. Probably you don't remember FP but he created accounts to attack Monegal at the very beginning. He was also very aggressive, but now we know who he is, where he had his surgery and where he is from. He had as many accounts as Lluser and Mr Sarcastic. His writing style was different from them too. There would be 3 groups of troll accounts then, apart from independent trolls.
Apart from linguistic evidence, I have contextual information, since I live in Barcelona and I'm very familiar with Dr Monegal's patients, their stories and backgrounds. The type of information these guys post is different. LLuser related trolls post crap that is (remotely) linked to reality. It's obvious he was here or met someone here who gave him that information. His motivation is revenge. Other trolls post complete crap that has nothing to do with reality. I'm still wondering how someone can find this funny.
Here you have what I know.
Best regards for you all
