If you have self excluded from sites there isn't much you can do unless you are able to reverse this by contacting the bookmakers directly.
It is important to note that if you self excluded yourself due to gambling problems or concerns then Matched Betting is not something that will be suitable for you.
Although Matched Betting is not gambling, we regularly use bookmaker and casino websites so the temptation to gamble will always be there.
If you do stray away from Matched Betting and begin to feel tempted to gamble we strongly would encourage you to seek support from some of the professional organisations that have been set up to assist with these issues.
You can easily self-exclude from all betting sites using GAMSTOP - https://www.gamstop.co.uk
The GamCare website also provides ongoing professional support - https://www.gamcare.org.uk
