How to prevent and fight spam

It's annoying to receive any type of unwanted comments and trackbacks. To prevent this from happening to you, check out these settings below:

1. Go to [Settings]→[Restriction Settings] type in the spammer's IP/Host.
2. You can also go to [Restriction Settings] from [Comments]→[Blacklist]
3. When you don't want specific users to leave comment on your blog, you can type in the user's IP in the [Reject IP] field and click on [Update].

Note:
*Only one IP address per line (or one keyword per line).
*This setting can only prevent users from commenting on your blog, but cannot prevent them from viewing your blog.
*For example: If you prohibit "blog60.fc2.com"then all users who are on the blog60 server will be prohibited.

In addition to the settings above, we also recommend that you send us notices through [Spam Inquiry]. Together we can help fight spammers!

Approval Settings

This setting can help you catch spam comments before posting on your blog. Just simply go to "Comment Settings"and under the comment settings you will see a display like the image below:


The initial setting is "Instant Display", change it to "Display after approval"then save the change.
You will receive a notification whenever you receive a comment or trackback, after you change the setting. You can also approve or deny the comment or trackback from the notification you received in your mail box.

Prohibit Rule (Regular Expression)

To better help our users to fight spammers, FC2 created a new feature called the "Prohibit Rule".

The Prohibit Rule is made up of special marks which is often seen in the JavaScript language. It helps to match words that you don't want to show on your blog. It can also list a certain type of entries or IP addresses to your blacklist.

If you select [Don't apply], comments or trackbacks that contain prohibited words will be rejected.
However, if you select [Apply], it gives you more specific options to reject a comment or trackback.

Here is a quick overview of how the Prohibit Rule works:

Example 1: When rejecting a [xxx.hoge.ne.jp] IP format:
Please enter *\.hoge\.ne\.jp
So any comments or trackbacks from [xxx.hoge.ne.jp] IP format will be rejected in the future.

".","*",and "\.hoge\.ne\.jp"symbols stand for:
. = The dot matches a single character, without caring what that character is. The only exceptions are newline characters
* =Quantifier(Greedy) 0 or more times
\.hoge\.ne\.jp = Any phrase that contains this word

Example 2: When rejecting [ntoska123456.oska.nt.ftth4.ppp.infoweb.ne.jp]:
Please enter [oska.nt.ftth4.ppp.infoweb.ne.jp] or [ntoska[0-9]+\.oska]

"ntoska", "0-9", "+", "\.oska"symbols stand for:
ntoska = Any phrase that contains [ntoska]
0-9 = Numbers from 0-9
+ = Repeat more than once
\.oska = Any phrase that contains [\.oska]

This way it is easy to just type one line to reject all similar types of IP addresses.
It also reduces your blacklist space.

Use "Prohibit Keywords"for "Prohibit Rule"

Example 1: Enter keywords within a line [example1] [example2] [example3].
Please enter like this: example1|example2|example3

Example 2: To reject comment formats like: [392Hello there..] and [348The recent efficient rate is 97% ww]
These are commonly seen spam comments. They usually start with three digits.
In this case, you will enter [^[0-9]+|Hello there|efficient rate|97%].

Usable Special Characters:

. = Any character (except newline)
* = 0 or more times
+ = 1 or more times
? = 1 or 0 times
^ = Beginning of the line
$ = End of the line
\ = Escape (enable or disable meta character meaning)
| = Alternation
( ) = Group
[ ] = Set (character class in character class)
{ } = Specified amount
