How to make forum "bot" that posts adsense ads?

What do you mean by "normal advertisements"? I think there's no need for a bot to add "normal" (or static) ads (for example, in the header, or footer).

 

No like selling own ad space and have bots to post them set the quantity

 

I've solved the problem (only for phpBB)! I've explained it, step by step here:

Sorry, you will have to copy and paste the address in your browser. You can also see it working there.

 

Here it is, step by step:

1. Open viewtopic.php

2. Find:
$row_color = ( !($i % 2) ) ? $theme['td_color1'] : $theme['td_color2'];
$row_class = ( !($i % 2) ) ? $theme['td_class1'] : $theme['td_class2'];

3. Replace with:
$row_color = ( !($num % 2) ) ? $theme['td_color1'] : $theme['td_color2'];
$row_class = ( !($num % 2) ) ? $theme['td_class1'] : $theme['td_class2'];
$num ++;

4. Find:
'U_POST_ID' => $postrow[$i]['post_id'])
);

5. After, add:
if($i == $ad_after)
{
$row_color = ( !($num % 2) ) ? $theme['td_color1'] : $theme['td_color2'];
$row_class = ( !($num % 2) ) ? $theme['td_class1'] : $theme['td_class2'];
$num ++;

$mini_post_url = append_sid("viewtopic.$phpEx?" . POST_POST_URL . '=' . $postrow[$i]['post_id']) . '#ad';
$template->assign_block_vars('postrow', array(
'ROW_COLOR' => '#' . $row_color,
'ROW_CLASS' => $row_class,
'POST_DATE' => $post_date,
'POST_SUBJECT' => 'Advertisement',
'MINI_POST_IMG' => $mini_post_img,
'POSTER_NAME' => 'Advertisement',
'POSTER_RANK' => 'Advertiser',
'MESSAGE' => '<div align="center">Ad code here</div>',
'L_MINI_POST_ALT' => $mini_post_alt,
'U_MINI_POST' => $mini_post_url,
'U_POST_ID' => 'ad')
);
}

6. Save, exit and publish the file.

 

Okay but for MyBB?
