There's a lot of comments about "players" that don't play and lock games. As some have pointed out, many of these are search engine spiders trying to index your site.
To prevent spiders from indexing a page or following links from that page, put the following line in the header section of pages not to be indexed:
<META NAME="ROBOTS" CONTENT="NOINDEX,NOFOLLOW">
You might want to let them index a game's main page, but not follow links (and consequently lock games) with the following:
<META NAME="ROBOTS" CONTENT="INDEX,NOFOLLOW"> |
