We do moderate the forums, and in the line of that duty of moderation comes programs which edit the way LFS functions, depending on the amount of editing the program does, determines the possibility of allowing it into LFS. If a program changes one thing, and we aren't sure and discuss it ourselves and still aren't sure, of course the devs step in and provide us with feedback as to whether or not the program should be allowed or not.
And just so you know, if a program slips through, we will track it down and decide if it is worthy or not to be allowed into the community.
Bob is not lying to you, I (albeit only once) have already checked one addon to LFS, but that was a long time ago.
Of course if the devs find it necessary, say if one program is getting out of hand and causing mass deconstruction of LFS as a program, the devs will take action on that third party software.
