You can't really do anything to handle people like Kryptonite. The best way is ignoring them until they shut the hell up and leave themselves, until then you can just listen the drama queen whining about nonsense, without proper facts.
How do you think people would have known of your team? I mean how do you suggest people to check? You just did 14 posts (as of today, before all this discussion you just had 2 posts) and you said you and your team were inactive. 14 (or even 2) posts are not many in these forums, so your signature (which you didn't even enable for one of your two posts before your return) is not spread and therefore not known. What else should they have done other than looking at LFSWorld and searching in the LFSForums? Google delivers way too many wrong hits (auto correcting dynamix into dynamic) and if they find your url, they get redirected to a photobucket picture saying "under construction". It could have been anything: A team in other sims or in racing games, a reallife motor racing team or teams that do horse racing (like the real life version of New Dimension Racing), bike teams, even some running (like marathon, triathlon a.s.o.) call themselves racing teams.
You said this was disrespectful. Do you respect things you do not know they exist?
Any kind of proof that your team existed before you came into this thread would be nice first of all. If your team wasn't registered then legally it didn't exist anyway, that is just the way the world works if you haven't noticed yet...and you, who have no idea about how things work in life, are talking about immaturity...oh the irony.
Right at the end of June, we're happy to announce that Pauli "Botswanan Salama" Peltokangas has joined us. Pauli comes from BBR-Team, where he spent long time mainly playing 5laps.com, but we're happy to see that he will slowly move into international racing. "Botsi" is known as a keen OW racer, but he has shown some great skills in UF1. In future hopefully Botsi will try to develop as a GTR driver and in other cars too.
