SE's most difinitive statement yet on parsers

[ispano]

If you're too ignorant to see that anything currently not allowed in the Tos that gives someone using them an advantage over someone that isn't. You might as well sanction teleport hacks and bots.

Read the post above yours. There's a world of difference between not allowing something because it's a parser and not allowing it because it's a third party program, REGARDLESS of what the program actually does. In this case, it's the latter, disallowing all third party programs. Has absolutely nothing to do with it being a parser, only that it's a third party program.
