/* This class is used to verify the homepage link of a user profile.

* of them points to the Friendica profile of the user, a verification
|
|
* mark is added to the link.
|
|
*
|
|
* To reverse the process, if a homepage link is given, it is displayed
|

* with the rel="me" attribute as well, so that 3rd party tools can
|
|
* verify the connection between the two pages.

|
|
* of the task is set to LOW, with the second case it is MEDIUM.
