We're constantly working to improve and shorten the time it takes to a page to load. In some cases, when a web page contains a lot of links (e.g Wikipedia), it might take some time for the page to load so WOT could check them all properly.
How to fix it?
By default, 'Reputation icons next to links' is set to 'Always'. You can easily change it and WOT can only show the poor ratings.
Go to settings-->Reputation icons next to links--> Show more-->Choose your preferences. We recommend selecting 'Poor only' so WOT could alert you from entering suspicious websites.
