If you need to remove lines with 3 or more occurrences of a character NOT in succession, try
This will also remove lines with 3 or more occurrences of a character in succession.
That approach isn't very robust. The first argument to gsub is an extended regular expression. If the line contains a ., it will match every character. If there's a ?, +, *, or some other metacharacter, there may be a runtime regular expression compilation failure.
What you're attempting can be done easily with grep and a single regular expression:

zgrep
ZGREP(1) General Commands Manual ZGREP(1)NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep is used to invoke the grep on compress'ed or gzip'ed files. All options specified are passed directly to grep. If no file is speci-
fied, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and
fed to grep.
If zgrep is invoked as zegrep or zfgrep then egrep or fgrep is used instead of grep. If the GREP environment variable is set, zgrep uses
it as the grep program to be invoked. For example:
for sh: GREP=fgrep zgrep string files
for csh: (setenv GREP fgrep; zgrep string files)
