Overwatch porn-related searched tend to stay in the top 20 most popular term searches on YouPorn, but it seems like the first week of the Overwatch League had a huge impact on the site.
When the Overwatch League was launched, the site saw a 26 percent increase in Overwatch-related searches. However, during the San Francisco Shock vs. Los Angeles Valiant match, overall traffic on the site went down 9%. The numbers continued to stay below average, but slowly went back up after the matches progressed.
Since there is very little data, it is unknown how much of this traffic decrease was solely due to the Overwatch League.
