This could be related to the bug I found last year that allowed one with 
Tabulator to edit other people's foaf graphs.

I think it is very important to very clearly separate assertions into graphs, and be very clear about who owns them. A weakness in the security here, can lead to mergings of different people's statements, which would lead to the results shown.

This is also a reason why I think to start one should avoid SPARQL Updates, and use much simpler tools. Form based entries are much better understood, and less likely to go wrong too. 

The jump into the semantic web should be taken carefully, small steps at a time.
