Tags such as Admin, Mod or police are forbidden due to rule §1.5 (I will quote it below). If you see people with these tags or tags that impersonate staff members or political figures is forbidden and feel free to report them in our website. Now i will quote you the rule.
§1.5 - Inappropriate use of language, communication and impersonation of any kind
-Using insults of any sort to put another user down. This can include but is not limited to racism, discrimination and or discussing/expressing (extreme) political, illegal or inappropriate situations/views.
-Linking or providing access to unsafe websites or content.
-Light insults such as "idiot" and "noob" are normally not punished, however, if abused they can be.
-Profanity without any insult is punishable. Bans or kicks are issued at our staff's discretion.
-Impersonating other users, political figures, Moderators or acting like someone who is more superior. This can be through the way you speak, sounds, your avatar, your license/interior plates, username and/or your game tag.
-Sharing personal details, including links to social media accounts, about other users is not allowed.
-Avatars, usernames and in-game tags need to be appropriate and cannot contain offensive content in any way. Your name must consist of at least four alphanumeric characters or else it will be changed by staff.
-No pornographic content or content of nude or sexual nature. This applies to any links posted, avatars and signatures, images uploaded, or content written.
-Behaviour that is considered to be threatening towards any user of our service is not allowed.
-Depending on the situation, this can also apply to other services that we use to aid us within TruckersMP.
CreatorInDeep's post in Caravan not showing up was marked as the answer
Dear @PioSki, at least for the standard caravan in TMP you need to have at least one skill point for Just-In-Time-Deliveries and Fragile Cargo in order to get the caravan trailers. If you are lacking these skill points on your profile, you simply won't see any caravans in the freight market. I don't know if you need the same skill points for the SP-mod, but it might be worth checking if you got these skills on your used profile.
