If you see any threads just flag them up and we'll take care of them.

yea, im also looking for some solutions. Although this is neverending battle...

If you wish I can help with it for you. Iam programming on php (back end) and front end (js,css,html) at work, for ablout 2 yrs.
make
<input type="text" name="spablc" class="spablc">
in login screen
in php write
if($_POST[spablc]){
exit();
}
in css file
.spablc{
display:none;
}
