I have looked at the three threads you have mentioned.
The threads are not disruptive, not offensive, not inappropriate or dangerous behaviour as are threads that should be reported here.
They are not duplicate threads as each offers a different service in it's own right, and are within the Code of Conduct, and the Forum Specific Rules of the Teamwork Forum.
Two of them were made in 2014, and have not caused any concern in those two years, so there doesn't seem to be a need for them to be of concern now.
