You won't get insta-banned from a server for just joining with it injected (due to the lack of server-side memory scanning) so as long as you're reasonable, I haven't gotten anti-cheat banned from a server unless I started to rage hack, I have however, been kicked by anticheat for bhop scripting.
TL:DR: You should be fine, just don't act dumb
EDIT: Placing objects that you can shoot through and also having esp on is great and often doesn't warrant the use of aimbot, with esp, there is no chance of an automatic ban
