We try to test many plugins that can work optimly with Linkilo. Link Whisper does something similar to ours, by creating a databased and search your site for possible link suggestion. Running both Linkilo and Link Whisper might cause BOTH of the plugins not stop or slow down your server and if your server is getting clogged, we might not be able to find the best link suggestions for you. So this feature will detect if you have activated both Linkilo and Link Whisper and ask you to deactivate Link Whisper.
