Schmidt | Hi,
watts yesterday, withal small rake-Captcha, over my Guestbook[...]  zugespamt.
have straight a small bath-Word-list added.
what are so The häufigsten Wörter/criteria to whom one effectively Spams filter out can? my list sees straight so from.
$spots += 1 * substr_count(strtolower($content),'<');
$spots += 1 * substr_count(strtolower($content),'>');
$spots += 1 * substr_count(strtolower($content),'!');
$spots += 2 * substr_count(strtolower($content),'</');
$spots += 2 * substr_count(strtolower($content),'100%');
$spots += 2 * substr_count(strtolower($content),'viagra');
$spots += 2 * substr_count(strtolower($content),'porn');
$spots += 2 * substr_count(strtolower($content),'free');
$spots += 2 * substr_count(strtolower($content),'poker');
$spots += 2 * substr_count(strtolower($content),'https://');
$spots += 3 * substr_count(strtolower($content),'href');
Please no misery long word-lists post, separate only potenziale Spam-terms, which one normal User probably eh never use would. About 5 Points show I momentarily Spamverdacht.
How can itself yet to Spams protect?
Greeting.
Julian

is me already noticed, white but not very where the Error lying.
do at not existence the Session The Session produce. and at Übertragen the Solution the Captcha by mail The Session by unset() Remove.
Haste You ne idea Why the lying could.
do my Sessions now code, if still time someone The Session ID rausbekommt. I do first circa a Key strain and subsequently by Base64 code. |

Julian
Schmidt | | it may be, that the trouble lane is. at least is it not at me again aufgetreten. I do now with none Request The Sessions zurücksetzen. |

this is not meaningfully, The SID is ohnehin public -
only The dahinterliegenden data (lying on the Server) are not public but
The can You do not by code the SID protect.
>>Haste You ne idea Why the lying could.
Perhaps. was my Session yet of yesterday active. lying/ lying well one logisches trouble
to. |

meant too that I The data in the Session verschlüssele.
because of Session Fixation Have I now too SID Regenerierung activate.

| clear can it, is utterly futile such distinction with good Bots, self then, if
The task time sounds "grau eingeben" or "schwarz" prompt. too
Buchstabendrehen isn't really one obstacle if The letters simply in the
Eingabereihenfolge of left to right geparst go can.
such Untermalung with gray letters helps the offered even To discern,
with welchem Captcha-type it it wohlmöglich To do has. fundamentally can
well say, that if The letters well To discern are and unless about
one "Sinn" To erkennnen is (something like How "was is larger: apple, auto"), then find
Bots relative light ways. but too with abverlangter Sinnerkennung How "was is
larger: apple, auto" there already simple Algorithms, The even very good
Trefferquoten to achieve.
unsure:
Mittelsicher but too badly To reading:
sure but too badly To reading:
and yet More safety afford The here in the Topic besprochenden Mechanismen
and the so begot Result can even well reading. |

Schmidt | Jup, there only not basiernd on JS, separate on Gifs. Can such moving Gifs too by PHP produce?
iF (05.05.13)
by me watts even but 1 Wrong Image displayed, means one not to that others fit. After F5 was everything IO.
is immernoch now and than so. hang well igendwie with the Browsercache together. Haste ne idea? |
|

| gives ne ext. class circa Anigifs with PHP to create but it would the thing insofern
not dienlich there not safer would as your principle.
Related to the incorrect Image comes of a logischen trouble in the Source -
there remaining you well nothing moreover as drüber To grüblen.
I wrote Yes the You vlt. rather the Captcha or. The Formel beget go ahead
Session-Beginn - means only once. at least circa first To look whether You so
the trouble into handle get. |

Julian
Schmidt | Mach The Session too only once so.
$_SESSION['rechen_captcha_pic']++;
if (!isset($_SESSION['rechen_captcha_spam'])) {
$_SESSION['rechen_captcha_pic'] = 1;
...
$_SESSION['rechen_captcha_spam'] = ...
}
$img = imagecreatetruecolor(80,20);
...
Evtl. lying the Error sooner at zurücksetzen the Session.
Habs so.
in the principle eig always. |
