+#### ORTB Blocking
+RTB House supports blocking advertisers in `badv` and categories in `bcat` parameters.
+The blocked advertisers/categories list has no length limitation, but response timeout is more likely to occur as the number of entries grow.
+Blocked advertisers list (`badv`) is an array of domains as strings.
+Blocked categories list (`bcat`) is an array of IAB categories as strings.
+
+For example:
+```
+pbjs.setConfig({
+  ortb2: {
+    badv: ["domain1.com", "domain2.com"],
+    bcat: ["IAB23-1", "IAB23-5", "IAB25-3", "IAB25-2"]
+  }
+)};
+```
