If he were serious about this lawsuit and the “defamation” he’d retain counsel in the relevant countries. The easiest place for him to do so would be the UK due to his citizenship and the libel laws there. But the problem for him is that the two UK “defendants” are the Lathams, who have done little more than comment on information either handed to them or commented on by Lloyd himself.
In the UK, he has another problem. British courts require that plaintiffs pay a deposit to the court as "security for costs." This is required for the protection of defendants, because the plaintiff is liable for the defendant's legal fees if Plaintiff does not win the lawsuit. Additionally, UK barristers are extremely expensive. I had a situation years ago where I had to hire a barrister in the UK, and it was very expensive compared to the price of a US lawyer.
Suing 7 non-Croatian citizen/residents in what amounts to the butthole of Croatia in Sisak is akin to asking the sheriff from the Dukes of Hazzard to serve Putin with an arrest warrant.
I believe that Sheriff Roscoe P. Coltrane has a better chance of arresting Putin than SlobLloyd's chances of prevailing in a lawsuit for defamation in this situation. SlobLloyd does bear some resemblance to Boss Hawg, but the actor who played that part was better-looking than SlobLloyd.
