Common Keywords and Themes Associated with These Calls

Users’ search terms provide a clear insight into the recurring themes that spam callers use to lure their victims. The most commonly used words include:

Iberdrola: Often mentioned as the company behind solar panel offers.
Solar Panels: Indicative of the product or service being promoted.
Hang Up / Cut Off: Reflects user frustration with abrupt disconnections.
Appointment: A common tactic to book consultations.
Finetwork: Another company name that sometimes appears in these calls.

These keywords indicate that the scammers are employing a multi-pronged strategy: using reputable company names to gain trust and then pressuring the recipient to engage in an appointment-setting conversation. The call scripts might begin with a polite introduction, but the follow-up questions can feel invasive as they ask for personal information and attempt to gauge your willingness to commit to a service.

The Role of Telemarketing and Scam Tactics

Telemarketing Tactics

Telemarketing calls, such as those reported from the 621-prefixed numbers, generally follow a structured script. The goal is to promote a service or product—often with the promise of free consultation or installation (as in the case of solar panels). Even when the approach is polite, the insistence on securing an appointment can be overwhelming.

Alleged Scam Indicators

Beyond standard telemarketing, some calls have been flagged as “alleged scam” due to the following:

Use of Personal Information: Callers often address you by name, which can make the call seem legitimate but is actually a red flag.
Pressure Tactics: Repeated calls and insistence on confirming appointments, even after you say no.
Incomplete Conversations: Calls that only ring or hang up quickly, which might be a technique to confirm active phone numbers before a more aggressive follow-up.

Users have shared sentiments such as “Don’t call me anymore…you idiots, don’t you see that you’re blocked?” and noted that the calls tend to be insistent and heavy, suggesting a possible organized scam network.

Comparative Analysis: Telemarketing vs. Scam Calls

To further understand the nuances of these calls, it is helpful to compare telemarketing calls with scam calls:

Aspect	Legitimate Telemarketing	Alleged Scam Calls
Initial Approach	Polite, offering free consultations	Use of personal details to create trust
Script Consistency	Follows a regular script; can be predictable	Varies with some calls disconnecting abruptly
Frequency of Calls	May call during business hours; frequency is moderate	Often repeated multiple times with a high degree of persistence
User Interaction	Seeks to set up appointments; willing to answer questions	Pressures the user; may ask for personal details without clear purpose
Response to Refusal	Accepts no as an answer	May ask for reasons or persist even after a clear refusal

This comparison highlights that while both types of calls can be annoying, scam calls are generally more intrusive and potentially dangerous, as they aim to harvest your personal information.

Potential Risks Associated with These Calls

Financial Risks

One of the primary dangers of answering spam calls is the risk of financial scams. Scammers may ask for bank details, credit card information, or even offer “too good to be true” deals that lead to hidden fees.

Privacy Invasion

When scammers use personal information—such as addressing you by name—they breach your privacy. This can be especially concerning if your data has been sourced from a leak or an insecure database.

Psychological Impact

Constant spam calls can cause stress and anxiety, making you feel harassed or unsafe. Repeated exposure to such calls may also desensitize you, making it easier for scammers to catch you off guard in the future.

Security Threats

In some cases, scammers might attempt to trick you into downloading malicious apps or clicking on harmful links that compromise your device security.

The Bigger Picture: Why These Calls Persist

Economic Incentives Behind Spam Calls

Spam calls and telemarketing scams are driven by economic incentives. Even if only a small fraction of recipients engage with the call, scammers can earn significant sums. This profitability encourages them to refine their techniques and target more numbers.

Use of Advanced Technology

Scammers employ advanced technology to mask their identities and mimic reputable companies. Techniques such as caller ID spoofing make it challenging to distinguish between legitimate calls and scams. This technological sophistication is one reason why numbers with the 621 prefix, like “telefono 621677291,” continue to be problematic.

Regulatory Challenges

Despite efforts by regulatory bodies to curb spam calls, these schemes often operate across borders, complicating enforcement. Spain’s telecommunications regulators are working to implement stricter controls, but the rapidly evolving nature of technology means that scammers continuously adapt to new defenses.
