Yes
I know it is slow. I'm trying to find a solution.
It seems we have single connections all over the world. Blocking them would also affect regular users.

Scorched earth approach:

when nrOfSingleConnections > 1000 then StopAcceptingConnections(timeperiod).

Right now it is unbearable and unusable anyways so it doesn't really matter anymore.

ATM I'm dropping and insane (IMO) amount of /16 networks which seems to help a bit.
This might affect regular users. I'll try to find a better solution in the future

It does indeed. But have you noticed that whomever this is doing is pushing and pushing. New records all the way.

Isn't there a list of known scrapers and their ip-ranges that they use ?

If not then it looks like a losing battle I'm affraid, hence the suggestion.

Nevertheless thank you for trying Marc 👍

From the requested URLs it looks like they are scraping the forum as guest for user profiles (which are only visible to registered users)

Interesting.

Not knowing the setup of the server any possibility to automate and serve another page to those that repeatedly do (if done so repeatedly from the same IP) or would that result in a ddos result ?

What could be the reason?  Try to login for each accountname with some standard passwords ?

No idea, the user names are not visible for guests

It may have something to do with https://www.cve.org/CVERecord?id=CVE-2024-7438

Any way I've installed a rewrite rule redirecting a common pattern and disabled the blocking of subnets (so valid users can access the forum again)
They still access the server, but their requests aren't handled by the PHP engine (reduces the load)

Is anyone else able to see user profiles? Even when logged in I get nothing but a page mentioning cookies.

Tested (with a normal user account / not just with admin): Yes I can see profiles as before.

I'm experiencing it myself too. At the moment I cant really pinpoint the problem. The server isn't that busy atm. And its connectivity is fine. But still slow responses

Marc
There is a risk that it happens again in a few hours. The visitor count is again disproportionnally high at 7:55 gmt.

Hi
I counted back ~8 hours from when it started here in Denmark(gmt+1) and came to the conclusion, that /something/ is "Scraping" at night in/from the US, but that's just my naïve little brains, thinking so...  :D

Hey,   ...hold on, it could also be yet another TAX from the "Trumpster"  >:(

Giggling regards Benny

Marc, again, seems to have chosen a practical approach, since the site is still responsive.
