The LW devs were not even aware the chat had stopped working until AFTER the Beta came out. As of yet, they've yet to release another beta or regular version but they promised to fix it.
Freeloaders are not really that easy to detect. I've browsed someone & it showed zero results of shared files. 15 mins later they had 600 odd, 20 mins later about 60, etc. This has happened so so many times. Sometimes the browse function is not reliable & does not always show the total no. of files a user is sharing. I can only guess this is due to lack of slots or busy & lack of bandwidth to mirror or obtain any search results during the browse search. This issue of browsing to see if someone is sharing or not has been debated for 2-3 years already. Browse is simply NOT a "definitive" method of finding this out.
