it's so sad to see many spam post in this forum, has been long using oxwall and i want to share little tips that might be help for oxwall.org and oxwaller to minimize spam poster. Maybe it's sound ridiculous and im stupid but my site is free from spam poster. here is what i do, im cloudflare user either but cloudflare also send spam traffic so stop using them. install mod security , you need to erase some rule to make it not blocking real visitor or whitelist the rule. turn off your ssh server if not needed or use key auth.
