[Help] Advanced WAF [Blind Injection]

I tried guessing a few column names from the admin table, but I got no luck....I counted the columns, there's 81, and I can't be fucked to get the column names letter by letter for the whole site.

So here's my syntax, it blocks table_name, if I can get around it, it would save me about 10 hours of time lol.

Here's my syntax, I tried a few commenting and a few other things, no luck.

Code:

www.natalpress.com.br/humor.php?id=7775+and+ascii(substring((select concat(column_name)+from+information_schema.columns+where+table_name=0x61646d696 ​e+limit+0,1),1,1))>0
