Those should both trip HTML_FONT_SIZE_TINY.
Unfortunately, that's a low scoring rule due to some FPs and limited number of
spam hits in the 3.0 corpus. The FPs may or may not be corpus pollution based.

inserting "<!---text--->" in the middle of "key words"
HTML tags are completely stripped before normal "body" rules are run, so this
trick, or any other trick based on inserting tags, has no effect on SA at all.
Only rawbody or full rules could be affected.
The striping doesn't work with the font-size trick, as SA's body rules will see
"VIwhateverAGRA" for "VA<font size=0>whatever</font>AGRA".
