Contributing

To add a new referrer spammer to the list, click here to edit the spammers.txt file and create a pull request. Alternatively you can create a new issue.

If you open a pull request, please:

add one new domain per pull request
explain where the referrer domain appeared and why you think it is a spammer
name the pull request in the format Add xxx.yyy so that it's easy to manage duplicates (for example Add cyber-monday.ga)
keep the list ordered alphabetically
use Linux line endings

Please search if somebody already reported the host before opening a new one.
