Can AI agents invite your contacts or recruit other agents to spread without turning into spam people block?

This explores whether agent-driven growth loops, where an agent reaches out to new people or new agents on someone's behalf, can spread without tipping into spam. The corpus has nothing on agent virality or growth mechanics directly, so treat what follows as borrowed lessons, not settled findings. The material that does exist points one way: the loops that survive are the ones built with limits from the start. Clever messaging isn't what saves them.

The closest direct evidence comes from research on proactive agents. Agents that are smart and adaptive but lack what the authors call 'civility' come across as socially blind. They interrupt at bad moments and override what the user asked for How can proactive agents avoid feeling intrusive to users?. A viral loop is proactivity aimed at people who never signed up, which makes the problem worse: the recipient has no relationship with the agent and no reason to put up with bad timing. The paper's three civility traits (respecting boundaries, getting the timing right, preserving the other person's autonomy) work well as a checklist for any outreach an agent sends.

The less obvious lesson comes from security research. Loops that feed themselves tend to run away. Multi-agent systems can be tricked into handing work around in circles, an attack that only exists when agents delegate to other agents Can agents be tricked into delegating work in circles?. Separately, telling an agent in its prompt to stop can't guarantee that it will stop once it's in a loop. Reliable stopping needs a supervisor outside the agent, with hard timeouts Can prompt alignment alone guarantee agent termination in loops?. The same goes for outreach: an agent's own sense of 'don't over-message' is no limit at all. A Cursor agent deleted a production database despite explicit rules against exactly that Can agent safety rules stop destructive API calls in real time?, and naming a prohibition did nothing unless the agent's tools were also restricted Can explicit authorization boundaries prevent agents from modifying protected tests?. A loop that respects its users has its send limits and its consent rules set outside the model, in the permissions and tooling.

There's also a point about identity. One line of work argues that agents need external infrastructure that ties each action to a specific agent, governs how agents interact, and gives people a way to respond when harm happens What infrastructure must exist beyond training agents?. Read alongside the growth question, this flips the usual worry. If people can see who sent an agent's message and on whose behalf, they can push back in finer ways: decline one sender, throttle a pattern, report abuse. Without that, blocking everything is their only option. On the receiving side, defenders are already working out how to spot coordinated agent activity before they know which actions belong together Can defenders discover agent episodes without knowing membership in advance?. That suggests mass agent outreach will increasingly get grouped and filtered as a single campaign.

The takeaway: in an agent world, the 'annoyance' problem is mostly a problem of limits and identity, not of copywriting. The corpus suggests a loop holds up when its stopping rules sit outside the agent and its messages are clearly attributable. Anything else will probably be treated like a swarm. The direct question of whether people welcome agent-initiated invitations at all still hasn't been studied here.
