There is no way your standard play rating will be affected by blitz or rapidplay (allegro) events.

FIDE still only allows you to sort on standard rating on its website. (Do advance search for SCO)
Increments is becoming more popular for all chess events. This is particularly true for blitz where K+2N v K will be agreed a draw with increments but one player may play on with a fixed time. 3min +2 secs gives a better/fairer outcome where a good player is allowed to demonstrate his/her ability.
