How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

Share of active installs on each version of this plugin · 98% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

At the current install trend, crossing 3K+ in roughly 148 days.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from. A declining trend compresses what a buyer would pay.

Reviewers treat it as the working successor to Stop Spammers, with praise for blocking bad actors and surviving a PHP version change, though one asks where country level blocking and a migration path went.

   I’ve been using “Stop Spammers” before since some time but also noticed that development had stalled a few years ago. Until this new project emerged (and the old was renamed to Classic). Great to see the old good idea and functions while new functions being added in “Dam Spam”! For me this is the successor of Stop Spammers.

   Works well – we have a membership site and this helps to keep the bad actors out. It also sometimes blocks legit users, but has a pretty easy way to grant access.

   Hey, you say “Dam Spam is the modernized successor to Stop Spammers,” but the “Stop Spammers” has country level blocking feature, which is so good, and this crucial feature seems to be missing on Dam Spam, is it intentional?…also how do we migrate to Dam Spam, there isn’t any migrate button available..

   Our free site, [domain removed] has been around for over 30 years. For the past eight years, we used Stop Spammers, and due to unexpected PHP version issues, we switched to Dam Spam, which now works perfectly. After correcting an incorrect IP address in our CIDR entry in the block or allow list, we were able to do so. Thanks to Web Guy’s advice! I think Dam Spam is the better choice compared to Stop Spammers. This topic was modified 7 months, 1 week ago by threadi.
