that's what I thought blocking was.
I did catch an individual lifting things from my tree within minutes of my posting it. Said individual has the family line completely messed up, continued to mess it up despite plain evidence clearly indicating otherwise.
I emailed said individual with clarification after more than incidents within 2 days, the material was corrected, and their response did confirm that my material was lifted.
I've noticed the message that comes up when an object is attached to someone else's tree along with whoever originally submitted it.
Sharing information is a wonderful thing, and I don't mind, whether I'm 'credited' or not-but for someone to just toss the information around and deliberately neglect to verify they attached it to the correct person is uncalled for.
A minimum of effort in most cases results in making and tracing family history better/easier for everyone.
