It would be sensible to define your terms. Which sense of imply would you like us to guess you're using (imply 2. (Logic) to suggest or involve as a necessary consequence [Collins])?
...........................
The best ways to investigate this sort of claim do include looking in decent dictionaries.
Compare the first-given (and in a non-historical dictionary, this indicates frequency of this sense being the intended one) definitions for the transitive usage/s at AHDEL, Collins and RHK Webster's:
affect
.1. To have an influence on or effect a change in: Inflation affects the buying power of the dollar. [AHDEL]
.1. to act upon or influence, esp in an adverse way: damp affected the sparking plugs.[Collins]
.1. to produce an effect or change in: Cold weather affected the crops.[RHK Webster's]
So there is at least a connotation of a negative (in the sense of adverse) effect. The Collins definition pushes this reasonably close to denotation, but it's probably justifiable to average these analyses to get a general picture.
This is doubtless compounded by the most usual sense of the homonym:
affect[2] 1. To put on a false show of; simulate [AHDEL]
This is not to say that these vibes will be picked up identically by all people, and certainly not in all contestscontexts (The mass of a planet will obviously affect its gravity).
