Banning a user

Post by sigo1 »

I would like to know if it is possible to ban a user as well as his/her IP so that they wouldn't be able to register for the forum again. ? if yes how


also is it possible to delete the comment / post of a user while still keeping the thread up ?

This forum is for phpBB related discussions, not for support. Therefore I'll move this topic into the support forum.

Yes, you can ban user names and IP addresses. In the ACP's Users and Groups tab, look under the User security item on the left navigation bar.

Personally, I don't bother banning user names; I delete their accounts and posts. If their user name is obviously spam (like "Mr. Viagra"), I disallow the user name, too (often using wildcards to ban all names with "Viagra" in them).

Also, be careful about banning IP addresses. Some (most, probably) ISPs use dynamic IP addresses, so the loser you're banning today might be your friend tomorrow. That said, if the IP addresses are in a country you don't care about (for example, I don't care about traffic from spam havens like Russia or China), you can ban that whole IP range.

Of course -- as long as the post isn't the only one in the topic.

Well it can happen that a given user doesn't have always the same IP address, so for example you ban me based upon my IP address. A couple of days later I get a different IP address assigned by my ISP so I can access your board again, but at the same time somebody else can get my IP address meaning that you now automatically have banned somebody else.

Hi Pony could you please explain the bold words above better .
First, instead of copying an entire post to get two sentences explained (called "overquoting"), please just include the text necessary (like I did in your quote).

Some (probably most) ISPs don't assign clients a static IP address (there aren't enough to go around), so they reuse IP addresses when somebody disconnects (in dial-up days) or is idle or their IP address expires. So while the person you're banning may be at 192.168.66.66 today, your friend (or new visitor or potential customer) in the same country may get that IP address later.

Additionally, with proxies, it's easy for a spammer from one IP address to appear to be coming from another, so banning the IP address that you see bans anybody using the proxy IP address. (Some people use them for privacy.)

I would only ban IP addresses if they weren't in a country that I cared about or if the same IP address repeatedly violated my site across multiple days.

If that doesn't help, you may want to research this more. I'm by no means a network professional.
