First, don't get hung up on things that don't matter, and pick the issues you raise. For example, unless a log is going to be client facing, I'd not say anything about the emojis or other slightly unprofessional but non-harmful stuff they might add. Naming projects, if it is again an internal name, it maybe annoying and slightly immature, but as long as it isn't demeaning or adding potentially liability to the company (e.g. insulting/demeaning to a class of people, gender etc) leave it be. Hell, I used to name our servers after Dilbert and Simpsons characters back in the day, and I know many others that did similar things too. We also did characters from comic books etc, just a way to have a little levity to our pressures. Or when you have that one server or software that constantly acts up so you name it some evil villain name, that's just coping with the situation and trying to have a little fun. Squashing that can be very bad for moral, don't be the fun police. Anti-social behavior is a super broad term and could cover everything from the quiet person happy to just do his/her work but just not wanting to socialize; to someone actively being aggressive and threatening to others (the true anti-social behavior). People over use that term a lot, but taken in context of your post I'd say you aren't talking about quiet people who just want to do their job. In that case I'd still give them the benefit of the doubt and chalk it up to youth until proven otherwise. In other words, they need guidance on the proper methods, processes, structure and what is considered professional and unprofessional, they don't need judgement. When you do address an issue, don't do it confrontationally (e.g. don't start it with well your wrong stop doing xyz), be informative and give examples of how it could be embarrassing or hurt the company and their reputation. Like let's say logs will be seen by customers or may at some point you can see but maybe they are missing because of experience. Point out that having anything that makes the product look like it doesn't take an issue seriously could be detrimental to the company, and the perception clients will take away from it. Don't make it personal, and don't be judgemental or you'll never make any headway. You don't need to be "in charge" to lead, you just need to give respect, gain their respect and learn to inform, educate and leave the judgement at the door. I am not saying you are judgemental, don't know you, just that it is one of the most common issues I see with people trying to change a situation or who are becoming leaders.
