St. Lachtain's GAA changes 

Hello i received a notification a few minutes ago informing me of a rude remark I had apparentally left on the St. Lachtain's GAA page. This is not the first time I have received such notifications and similar incidents have occured in the past. I did not, in this incident as with the others make these alterations although I am in no doubt as to who did. My younger sibling wrote those things. I live some distance from my sibling in fact and have never made an account or an edit on wikipedia. My question is why am I receiving such messages, surely it must be obvious from the ip address? I agree the edits are unnacceptable but I am not is responsible for the child and his behaviour and would not like to be held to account as such. If you could get back to me on this I would greatly appreciate it.
