Certain things like translated chat macro reveals client editing when info is sent to the servers. Even in other foreign games like PSO2, people who are doing Language Patches all warn about linking certain stuff or using build-in chat macros. Also it depends on how lucky you are. If you always use the macro then there is a high chance that you used it when the AI is in high alert on suspicious activity. It's like speed cameras. No one knows when it will be activated so best not to speed at all.
Be careful especially when using F7. There is a disclaimer on that in the new patch.
If you ever need to find party, right click the leader's name and press "party request" rather than just pressing on that one small button beside the leader's name to send and automated with Blade And Soul Gold. The long winded right click request party thing will not send a PM over so unless there are other info that we don't know is being sent that might compromise on the risk of getting banned, you should be fine.
