The output is:

发帖数: 88 | 4 Your original regex means that there is a match when anything other than
2,3,4,6, or 8 appears in $1. What you what to say, is that if anything
like 2,3,4,6,or 8 appears, it does not match.
Use this
awk '$1 !~ /[23468]/' input.txt
notice the ! before ~, and the removal of ^
