Footnotes without numbering and without horizontal rule

This is similar to Footnotes without numbering question here Footnotes without numbering but it won’t let me add a comment and this isn’t an answer..

When I add letfootnoterulerelax as in order to suppress the horizontal rule as suggested in the comment to the answer, such as this MWE:

documentclass{article}
letsvthefootnotethefootnote
textheight 1in
newcommandblankfootnote[1]%
  {%
  letthefootnoterelaxfootnotetext{#1}%
  letfootnoterulerelax%
  letthefootnotesvthefootnote%
  }%
letsvfootnotefootnote
renewcommandfootnote[2][?]%
  {%
  ifrelax#1relax%
    blankfootnote{#2}%
  else%
    if?#1svfootnote{#2}elsesvfootnote[#1]{#2}fi%
  fi
  }
begin{document}
First Footnote herefootnote[]{footnote 1} next footnotefootnote{footnote 2}
Force footnote number 5 herefootnote[5]{footnote 3 numbered 5}.

Anotherfootnote[]{footnote 4} footnote here.

And foot notefootnote{footnote 5} 5 here.
end{document}

It suppresses the horizontal rule for all footnotes. How can I suppress the horizontal rule for some footnotes but not others?

documentclass{article}
usepackage{newfloat}
DeclareFloatingEnvironment[fileext=cmt,placement=b]{Comment}
setcounter{bottomnumber}{3}% max bottom floats per page
newcommand{comment}[1]{begin{Comment}normalfontfootnotesizeparindent=bibindent #1end{Comment}}

usepackage{lipsum}

begin{document}

lipsum[1-5]
