Replytocom redirector plugin solves a problem with some bots that do not know how to handle the replytocom parameter as part of a wordpress url.
If you see those requests in your log and this annoys you, than what the hack. If not, don't.
For us atleast:
There are others, but not so annoyingly, seems like google is not really affected by this, although a search for replytocom returns too many results so maybe its just us.
Look at your logs, grep replytocom and see that spiders get a 301 result
Just let us know on the forums here, or on our site
Yes, you can probably do this in htaccess and other ways, but this is a simple and targeted solution for this simple problem
Again, just let us know
Not by much, we saw this, wanted to solve it - so here it is, you are always welcomed to try transposh out at transposh site
