I have noticed some vips doing it to troll their teammates and I've personally dealt with them accordingly. Removing TNT altogether would not fix the issue for two reasons:
1- It can spawn on a map and they can do it anyways.
2- If you crash because of it, then it's a client sided issue and removing tnt won't help, any explosion will put you at risk of crashing.
What I can suggest for you to do is next time that happens, take a SS and upload it to the clan's forums under the report a player section, the administrative staff will deal with him/her accordingly.
