Hey there, sorry you’re having a bad time after just joining.
This topic might help clear a lot of things up, as it spells out exactly what you need to do in order to increase to the next trust level.
Also, as far as I know, the welcome bot is not something that CoG has the ability to change, as I’m fairly certain that’s something that comes with using Discourse.
Regarding the like limit, I have reached the like limit so many times, as have many others. I don’t think it’s anything that the staff can change either, and it’s just one of those quirks that you have to bear.
