Profit Accumulator members have had access to more than £12,000 in 2017 so far.
The 'how to make £1,000 a month' thread in the matched betting forum lists offers with the aim of hitting that target every month.
There is also a 'how to make £300 a month' thread aimed at members with less time to spare. The running total for this thread so far in 2017 is £3,764.
Access to the forum threads requires full PA membership, which is available for £1 for three days.
The offers are guaranteed profit - so the thread does not include offers that require an element of luck, such as acca refunds, price boosts.
The monthly profits are often more than £1,000 or £300 - as shown by hitting the £12,000 mark in less than nine months.
March was the most profitable month of 2017 so far, thanks largely to the Cheltenham Festival.
