Anything wrong with mylot search ??

Tweet

As per mylot terms,we should check whether some one already started similar discussions we intend to start.In the morning I wanted to start discussions regarding few PTC sites .I typed the famous ptc site's name in the mylot search bar and clicked search discussions button.I got no answers other than few google ads.After some time I used the search bar again to find previous discussions regarding a very popular ptc site.Again I got no leads,except a reward of 2 cents.Is this happening only to me ??
